THE STEREODYNAMICS STUDY OF THE C(P-3) plus OH (X-2 Pi) -> CO(X-1 Sigma(+)) + H(S-2) REACTION

The stereodynamics of the title reaction on the ground electronic state X-2 A' potential energy surface (PES)(1) has been studied using the quasiclassical trajectory (QCT) method. The commonly used polarization-dependent differential cross-sections (PDDCSs) of the product and the angular momentum alignment distribution, P(theta(r)) and P(Phi(r)), are generated in the center-of-mass frame using QCT method to gain insight of the alignment and orientation of the product molecules. Influence of collision energy on the stereodynamics is shown and discussed. The results reveal that the distribution of P(theta(r)) and P(Phi(r)) is sensitive to collision energy. The PDDCSs exhibit different collision energy dependency relationship at low and high collision energy ranges
