Abstract

We report the femtosecond dynamics of the vibrational motion in the transition-state evolution of an isomerization reaction. The observed nonstatistical and bound behavior reflects the localization in selective torsional and bending modes (of the 72 normal modes of the system). The multidimensionality of the potential energy surface is examined by comparing experiments with theoretical calculations.
