On the basis of unimolecular and collisionally activated decompositions, as well as their charge stripping behaviour, [C 7 H 8 ] + ˙ and [C 7 H 8 ] 2+ ions from a variety of precursors have been studied. In particular, structural characteristics of molecular ions of toluene, cycloheptatriene, norborna‐2,5‐diene and quadricyclane have been compared to those of [C 7 H 8 ] + ˙ and [C 7 H 8 ] 2+ rearrangement fragment ions obtained from n ‐butylbenzene, 2‐phenylethanol and n ‐pentylbenzene. Severe interferences from [C 7 H 7 ] 2+˙ ion fragmentations have been observed and rationalized.
