Effect of Vibrational Excitation on the Stereodynamics of Reaction O plus DCl→OD plus Cl

The effects of vibrational excitation of reagent molecules on the stereo-dynamical properties of O+DCl -> OD+Cl reaction were discussed via the quasi-classical trajectory (QCT) method. The polarization. dependent differential cross sections (PDDCSs), the polar distributions of P (theta(r)) and P (phi(r)) were calculated. The results show that the initial vibrational excitation of the reagent molecules has considerable influences on stereodynamics of the title reaction. When the reagent molecules are excited to higher vibrational levels the rotations of product molecule prefer to parallel to the scattering plane, in other words, "in-plane" mechanism.
