The mass spectrograms of fourteen benzo[ a ]‐ and benzo[ c ]acridines, several of which are carcinogens, have been determined, and the following main features emerge: (a) presence of strong peaks corresponding to several stages of dehydrogenation; (b) very little fragmentation of the polycyclic frame, with, in ethylbenzacridines, a noteworthy splitting of methyl groups; and (c) importance of the double‐charged ions, some of which contribute more to the ionic current than do the corresponding single‐charged ones. The pattern of the spectrograms can vary considerably with the position of the substituents.
