The kinetic energy released in the major charge‐separation reactions of [C 7 H 8 ] ++ [C 7 H 7 ] ++ and [C 7 H 6 ] ++ formed from toluene, and in the corresponding reactions of toluene‐α‐ d 3 , toluene‐ d 8 and 2,3,4,5,6‐toluene‐ d 6 has been measured. Some fragmenting [C 7 ] ++ ions are linear; in certain cases they have cyclic structures while in others ‘coiling’ of a linear ion to allow hydrogen transfer in the transition state is suggested. From relative metastable ion abundance data it is apparent that nearly complete H/D randomization accompanies these slow reactions.
