Abstract

The quasiclassical trajectory method is used to determine the dependence of the cross section and threshold energy for reaction upon initial vibrational state for the reaction H + H2O(v1v2v3) → OH + H2. A significant rate enhancement is found when any of the three modes or combinations thereof are excited, but the enhancement is larger when the symmetric stretch or bend modes are excited than when the asymmetric stretch is excited. Enhancement efficiencies (the ratio of threshold energy reduction to reagent excitation energy) vary from 60% for H2O(001) to ˜100% for H2O(020) and (100).
