Dissociation rate of hot benzene

Abstract

The dissociation rate of benzene and d6-benzene were measured under collision-free condition by multimass ion imaging techniques. The value of 1±0.2×105 s−1 and 5±1×104 s−1 were obtained for benzene and d6-benzene, respectively, with internal energy of 618 kJ/mol. The dissociation rate of benzene with internal energy of 483 kJ/mol was too slow to be measured, and the upper limit of the dissociation rate was estimated to be 3×103 s−1.
