The kinetic energy released in the major charge-separation reactions of [C7H8]++ [C7H7]++ and [C7H6]++ formed from toluene, and in the corresponding reactions of toluene-α-d3, toluene-d8 and 2,3,4,5,6-toluene-d6 has been measured. Some fragmenting [C7]++ 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.
