摘要：Quasi-classical trajectory (QCT) calculations are employed for the reaction F + HO(0,0) -> HF + O based on the adiabatic potential energy surface (PES) of the ground (3)A '' triplet state. The average rotational alignment factor < P(2)(j'.k)> as a function of collision energy and the four polarization dependent generalized differential cross sections have been calculated in the center-of-mass (CM) frame, separately. The distribution P(theta(r)) of the angle between k and j', the distribution P(phi(r)) of dihedral angle denoting k-k'-j' correlation, and the angular distribution P(theta(r), phi(r)) of product rotational vectors in the form of polar plots are calculated as well. The effect of Heavy-Light-Heavy (HLH) mass combination and atom F's relatively strong absorbability to charges on the alignment and the orientation of product molecule HF rotational angular momentum vectors j' is revealed.
