INTRODUCTION For a number of years, the mass spectrometer has been applied to the elucidation of problems in molecular structure. Correlations of mass spectra with structure have now been made for almost all of the common types of organic compounds (2, 8). Most of these correlations by necessity, emphasize the type of spectral pattern or decomposition paths to be expected for a particular type of molecular structure. However, in determining the structure of an unknown compound, the reverse situation is presented — i. e., the prominentions in the mass spectrum are known, from which one wishes to determine the most probable molecular structure or structures. When the reference mass spectrum of the unknown has been run previously, this can be located from the prominent peaks, using a number of filing systems previously described (5, 6, 9, 11, 14, 15). However, it obviously is highly desirable to have an identification system not dependent on the availability of the standard spectrum of the unknown. This similar problem in other fields of spectroscopy has led to charts or tables indicating the prominent functional groups or other structural features which are found at particular wave lengths. Perhaps such tabulations have been most widely used in infrared spectroscopy — e.g., "the Colthup chart" (4). Aprevious suggestion for such a system for mass spectrometry (9) has led to the accompanying tabulation of mass spectral correlations. GENERAL DESCRIPTION In designing this table, the purpose was to provide,where possible, the empirical and structural formulas of ions that might be found at a particular m/e in a mass spectrum, plus an indication of how each such ion might have arisen. A further purpose was to give an indication of the probability of each such classification of ions occurring. Thus, the table should indicate possible ion structures and precursor molecules for each of the prominent ions in the mass spectrum of an unknown compound, with afurther indication of the general probability of their occurrence. The mass spectral data used in this tabulation were available in a card file (9) containing a card for each of the 10 most prominent peaks in the 4000 referenced mass spectra. These cards were filed serially by nominal mass number with separation within each m/e by order of abundance in the particular mass spectrum. Thus, at m/e 123 in this file there appeared a card for each compound in which m/e 123 was one of the 10 most abundant ions in the mass spectrum. Cards for all compounds in which m/e 123 was the largest peak in the spectrum appeared l

first, followed by those in which m/e 123 wasthe second largest, etc., through the 10th most abundant. To prepare the tabular correlation, each of the cards filed under a particular mass number was examined to ascertain the relationship of this peak in the spectrum to the structure of the compound. Where possible, the empirical and structural formulas and the mechanism of formation of the ion were assigned, plus the general structural type or functional group of the particular compound which gave rise to this ion. The number of cards under each such classification under the particular m/e were recordedfor each magnitude (second most abundant, etc.). Such data were accumulated for the three most abundant ions in all mass numbers filed (m/e 1-500), with less abundant ions being included for those mass numbers containing fewer cards in the three highest peaks. All 10 of the highest peaks in the spectra were included above m/e 218. Some ions were not included in the classifications because it was felt that they were not sufficiently representative of types of compound structures or functional groups. These are listed as the" P. I. D. ions," representing the "Parent" or molecular ions, ions due to isotopic species of smaller or artificial abundance — e.g., carbon -13 or deuterium — and doubly charged (or multiply charged) ions or other ions of fractional mass, as metastable ions. "Other unclassified" ions are those for which it was felt there was insufficient evidence of their structural significance for classification. PRESENTATION OF DATA m/e. The mass-to-charge ratio in the first column of the table is calculated from the assumed empiricalformula,using the atomic weight scale based on carbon = 12.000000. Almost all of the spectra used in this study, however, were run on instruments of insufficient resolving power to determine such fractional masses, so that it had to be assumed that eachpeak represented only one empirical formula. Thus, the significant figures shown are as calculated, not as determined. The correlations should still prove useful, however, where it is possible to determine the m/e of the unknown peak in question to millmass unit accuracies. As has been shown extensively by Beynon and coworkers (1,2), this will then make possible the assignment of the empirical formula within each of the unit mass classifications, and thus simplify the identification problem. There is a definite possibility that even the nominal mass number is in error, because of the very large number of spectra examined and the "uncertified" nature of these. This is especially true, naturally, at higher mass numbers, where resolution is decreased and mass markers become less reliable. However, many of these errors were eliminated because of the correlative nature of this study, and in doubtful cases, the peak was put in the "unclassified" section. The author welcomes correspondence on any errors which are found by readers, and hopes that such helpful criticism, as well as the increased availability of high resolution spectra — e.g., (3) — will largely eliminate such errors in later editions of this table. Empirical Formula. Only the ion of m/e of the most abundant combination of isotopes is classified.

because of the presence of natural or artificial isotopes, the remainder are classified under P.I.D. Thus in a particular spectrum if the C H5 ion is the most abundant, the C C H15 ion could well be the fifth most abundant. It is not classified, as its significance is usually fairly obvious from the presence of the larger C H peak. In the case of elements with more highly abundant natural isotopes, however, this leads to some possibly unexpected classifications. Thus, the most abundant CHBr2 ion is not that containing two atoms of the most abundant of the isotopes, Br . Because the Br abundance is nearly that of the Br , CHBr2 gives ions of m/e 171, 173, and 175 in a ratio of 1:2:1. Thus, a spectrum giving rise to the CHBr2 ion would be referenced only under CHBr Br , m/e 173, and the corresponding isotopic ions at m/e 171 and 175 would be tabulated under P.I.D. This should cause no difficulty in the identification of CHBr2 from an unknown spectrum, as the largest peak should be used first to identify the ion. Structural Significance. Where possible, the types of ions causing the empirical formula shown are postulated, and the abundant compound types found are tabulated separately. The justifications for many such structural classifications are due to careful correlations of spectra that have been published by a variety of authors. No attempt has been made to give proper credit or reference to this vital previous work. Such an attempt would seriously complicate the table, and it was also impossible to give proper credit in every case. The author found most helpful a number of unpublished correlations which had been prepared informally by coworkers in the Dow laboratories. In addition, a sizable number of interesting structure-spectralrelations were found which are reported for the first time in this table. The theoretical implications of these new correlations will be discussed in separate publications. The author has had the temerity to make structural classifications andpostulate correlations in many cases without rigorous proof. This is partially based on experience and intuition, but it is presumed that a number of such postulations will in time be shown to be incorrect. It is hoped that in most cases these will serve a useful purpose, even if only to stimulate the reader to point out such errors. Where the assignment is in considerable doubt, a question mark has been inserted and, of course, the most dubious cases have been listed under Unclassified. If there appear to be two ways in which the particular ion in the spectrum could have arisen, it is usually classified under the most probable. If this isuncertain or if it is felt the ion would be considerably less abundant if only one such structural influence were active, it is listed as Unclassified. However, at most mass numbers there are few cases of this. At m/e 57 a further breakdown of overlapping mechanisms was attempted because of the very large number of C H ions found. Thus, a second number is listed following that indicating the number of tabulations under the most abundant, etc., peaks to indicate those compounds in which a second structural feature influenced the formation of this peak. For example, in fer^butyl ethers the high abundance of t h e C H ion is caused by the ready cleavage both at the branched fer£-butyl group and at the alpha bond of the ether. +

A homologous series of compounds will be expected to show similarities in structural correlations. Thus, when the classifications for a particular empirical formula were found to be parallel to a lower member of the homologous series, reference has often been made to this lower ion instead of making a complete listing of the possibilities. Since the higher member of the series is usually not represented by as many compound examples in the mass spectral file, it may be that one or more of the structural types indicated for the lower member were not actually found at the higher mass. At m/e 200 and above, individual compounds are often listed with the inference that by checking lower members of the homologous series analogous possible structures will be indicated. For the individual compound the postulated mechanism of formation of the particular ion is usually indicated, followed by "etc." where it is thought that the other classifications foundfor lower members of the homologous series will apply here also. For example, at m/e 223, the structure "Cl(H C ) PhCH(CH )-, etc." is listed. Indications of other possible structures can thusbe found at m/e 189 (which refers to m/e 133) and m/e 209 (which refer s to m/e 125) which list molecules in which CI- and CH -, respectively, are replaced by H - . Thus through these cross references one can infer that at m/e 223 such structures as CI ( H C )PhC (CH ) - and CI (CH ) (C H ) PhCH (CH )- are also probable. A number of ion types are placed under P.I.D. (Parent, /sotopic, Doubly charged) instead of being classified separately. It is felt that the parent (molecular) ion is not representative of a structural type, but only of a single compound or group of isomeric compounds. Thus, the usefulness of the molecular ion for structure determination lies more in the indication of empirical formula for the parent molecule and in indicating the structural groups of the molecule through the difference in mass between the parent ion and other prominent peaks in the mass spectrum. The peak at highest m/e represents the molecule ion when the molecular has sufficient chemical stability - e.g., unsaturated or cyclic structures. As a further check, the parent will be an "odd-electron" ion with an m/e of even number unless the ion contains an odd number of nitrogen atoms (2, 8). An ion containing a less abundant combination of isotopes, also included under P.I.D., is not classified separately because identification is usually more simple from the more abundant isotopic combination. The mass number and relative abundance of isotopic ions can be calculated from the accompanying table. It might be argued that classification of these could be useful where the more abundant isotopic combination is obscured by another ion of nominally identical mass. This, however, will be an unusual circumstance and can be overcome by careful use of the table or by the use of exact empirical structure determination through high resolution techniques. Multiply charged ions, a third classification under P.I.D., are rarely of sufficient abundance to be included. Those that were found usually offered little apparent structural significance in addition to the corresponding singly charged ion and were much less abundant, although further work in this field may show helpful correlations. The most common doubly charged ions of sufficient abundance were 7

found in the spectra of fused ring aromatic hydrocarbons and generally arose from loss of one or more hydrogens from the parent ion. No metastable ions were found of significant abundance, but most of the spectra from the author s laboratory were recorded using a metastable suppressor to eliminate such ions. No attempt has been made to give the true structure of the ion, if it is actually other than that indicated by the nominal bond cleavages. For example, Meyer son and his coworkers (12) have shown that cleavage of the benzylic bond in aromatic hydrocarbons does not give the benzyl ion, C H C H , but the rearranged tropylium ion. Thus, the entry PhCH •£ R under m/e 91 indicates only the benzylic bond cleavage and not the rearrangement. Relative Probability of Ions. The final columns of the tabulation, headed 1, 2, 3, and possibly up through 10, show the number of compounds giving peaks of each relative magnitude under each structural classification. Thus, of the 212 compounds studied in which m/e 91 is one of the three highest peaks in the spectrum, 48 were found to be formed as the most abundant through the benzylic cleavage loss of an alkoxyl, alkyl, halogen, carbonyl, etc., group. Further, such a cleavage was found to produce the second and third highest peaks in the spectra of 18 and five compounds, respectively. Thus, one can draw the inference in attempting to identify a base (highest) m/e 91 peak in an unknown spectrum that one should first check for the possibility of the benzylic structure in the molecule. By similar reasoning a C H ion having a reduced intensity in an unknown spectrum would probably not arise from the C H C H - group, but from a more complex structure through a more drastic cleavage or rearrangement. The usefulness of this probability concept is admittedly in doubt, because the 4000 spectra cataloged, although a large number on the basis of known collections of mass spectra, are still only a small percentage of the total number of organic compounds in the literature. The distribution of structural types naturally depends somewhat on the interests of the originating laboratory and company. Thus, the large number of C H 0 C 1 ions tabulated atra/e 196 resulted from the study of a sizable group of trichlorophenoxy ester derivatives. However, the compounds of this file generally represent abroad range of chemistry, and a real attempt has been made to include also all classes of compounds whose spectra have been reported in the literature — e.g., steroids and hydrocarbons of high molecular weight. In general, the statistical data are probably meaningfulfor the" simpler" organic compounds, but of little value for more complex or specialized classes of organic compounds, such as plant pigments, perfluoroaromatic compounds, sugars, etc. Thus, the distribution of relative abundances should be given weight in structure indications generally only where quite a number of compounds of that type were available. For example, as cited above, the data for C H ions indicate that structures containing the benzyl ion have a high probability of giving this m/e as the highest peak in the spectrum. However, the absence of a large number of entries for C H S at m/e 123 does not indicate that the corresponding thiobenzyl(HSC H CH -) compounds could not give a very abundant m/e 123 peak. 1

When several structural types are listed for the same formula on one line, they are generally in decreasing order of importance. SYMBOLS † indicates that this bond is cleaved to form the ion. The group or groups lost, if indicated, are usually designated by general symbols such as R (alkyl) or Y (functional group). Ph †R †H indicates the loss of the R group with rearrangement of one of its hydrogens to the resulting ion (here Ph-H ). This should be followed by "(rearr.)." Theβ-hydrogenatom is usually the one rearranged (7), so that the lack of aβ-hydrogenin the compound should greatly reduce the probability of the rearrangement. A double cleavage such as CH COO † R † H indicates the rearrangement of two hydrogen atoms, although in this case the second hydrogen atom need not come from the carbon atom beta to the bond cleaved (10). † indicates two bonds are cleaved (usually not the cleavage of a double bond). RC (R')(R") † indicates that the bond broken is to the carbon atom and not to R' or R". (ABC) † Y means that Y might be substituted on A, B, or C. "Base" means the highest peak in the spectrum — i. e., the most abundant ion. A semicolon signifies that the classifications following it are significantly less abundant than the preceding ones. Above m/e 218 in the table the semicolon means that the classifications following it were only found as less intense than the fifth most abundant peak. ΣR indicates a summation of the alkyl groups — i. e., if R = C H , R'=C H , and R"=H, then ΣR = C H . (C F ). Parentheses around a formula indicate a significant ion (especially for exact mass determination) which was not in the card file, and is therefore not included in the numerical tabulation.

CONCLUSIONS Despite the fact that this file cannot possibly contain a representative number of all possible types of organic molecules, the prevalence of certain entries is of interest. A total of 15,746 peaks from the spectra of 4036 compounds were examined, and an assignment of structure and mechanism was attempted for each of these. The most entries are found at m/e 43, 41, 57, and 55, representing 5.8, 5.5, 3. 5, and 2. 6%, respectively, of the total entries for the three most abundant ions. Similarly, the most abundant empirical formulas found were C H 5 , C H 7 , C H 9 , C H 7 , C H O , andC H7+, representing 5.3,4.0,3.0, 2.4, 1.5, and 1.5%, respectively, of the total number of entries for the three most abundant ions. Figures A, B, and C represent the number of entries which were found for the first, second, and third most abundant ions, respectively, at each nominal mass number. The number of peaks to which no appreciable structural significance could be assigned ("other unclassified") was gratifyingly low. Separation between peaks classified as P.I.D. and "other unclassified" ions was not made for all m/ebelow m/e 103, but these types together represented only 11% of the total, so that the "unclassified" alone should be under 5%. At the higher mass numbers the "other unclassified" ions were 9% of the total. The fact that such a high percentage of the major ions in this wide variety of mass spectra are explainable indicates the potential of the method for molecular structure determination, and the significant progress that has been made within the last decade on the fundamentals of ion decomposition paths. Space has been left in the table, especially at the higher m/e, for the addition of correlations found subsequently by the reader. This, of course, will increase the usefulness of the tabulation in the areas of the reader's particular chemical interests. The author would appreciate it if any such additional correlations could be forwarded for inclusion in a possible future edition of the table. To reiterate, it would be very helpful to hear of alternative explanations of mechanisms for the data shown or of any errors found. Often the neutral fragment lost is of as much structural significance as the ion formed. Thus it should be possible to construct a similar tabulation using the mass of the difference between the abundant ion +

found and the molecular ion. With such a table, functional groups which ordinarily do not retain the positive charge on cleavage of the molecular ion, such as the methyl group, halogen atoms, etc., could be classified and more easily identified. Such correlations fail, of course, when the abundant ion is formed from a fragment ion instead of the molecular ion, but the incidence of such cases would be of interest. Preparing such tabulations with the file cards used in the present study should be simplified because degradation paths have already been assigned. However, the preparation of such a correlation should await an assessment of the usefulness of the present tabulation. In the past few years, the markedly increased use of mass spectrometry in the solution of complex problems in molecular structure has been most gratifying. It is hoped that this tabulation will encourage this use by directly aiding both the neophyte and expert in structure identification. Possibly of greater importance, however, isthedemonstration of the high percentage of the abundant ions in mass spectra to which meaningful structure assignments can be made, demonstrating the maturity of the method and the unique usefulness of its molecular structure information. ACKNOWLEDGMENT This paper embodies efforts and ideas of such a large number of personnel of the Mass Spectrometry Section of the Chemical Physics Research Laboratory of The Dow Chemical Co. That it should be called the "Dow Table" of prominent ions in mass spectra. The structure and principles of this table evolved from invaluable discussions with R. S. Gohlke over a period of several years. Among others whose contributions are gratefully acknowledged are Jo Ann Gilpin, Joanne M. Rupprecht, Marjorie A. Eash, William T. Shelburg, and Eugene O. Camehl. The author is also happy to thank Norman Wright and Victor J. Caldecourt for inspiration and counsel, Priscilla A. Turner for stenographic assistance, and Charlotte M. Cripps for tabulations.
