Classical trajectory study of infrared multiphoton photodissociation

Abstract

Classical trajectories on a realistic model potential energy surface (approximating one dissociation channel of CD_3Cl) driven by an external force have been used to model infrared multiphoton dissociation. This model predicts a reasonable energy density threshold behavior, and generally (except at extremely high power densities) shows random (RRKM-like) behavior of the highly excited molecules, although non-random effects are evident immediately after the field is turned on.
