Abstract
This article reviews recent progress in the study of ion reaction dynamics in which product energy disposal studies provide detailed information about the potential energy surfaces mediating chemical rea ction. We emphasize product state-resolved studies of the proton tran sfer and hydro gen atom tran sfer reactions of 0-. We also discuss several critical experi ments that test the validity of the double minimum potential energy surf ace model in describing the bimolecular nucleophilic substitution (SN2) reac tion. Photo ionization methods for producing vibrational and vibrational rotational state selecti ons of ions are also discussed, and recent examples with Hi and Nt are presented. The role of these state-selection methods in elucidating mode-s elective chemistry in the reactions of NHt and C2Ht are also discussed.
