Abstract:
The reagent rotational excitation effect on the stereodynamics of H+LiF→HF+Li is calcu-lated by means of the quasi-classical trajectory method on the Aguado-Paniagua2-potential energy surface (AP2-PES) constructed by Aguado et al. [J. Chem. Phys. 106, 1013 (1997)]. The angular distributions of vector correlations between products and reactants, P(?r) and P(Φr) are presented. Meanwhile, the four polarization-dependent generalized differential cross sections are computed. The results indicate that the reagent rotational quantum num-bers have impact on the vector properties of the title reaction. In addition, the reaction probability has been calculated as well.
Key words:  Stereodynamics, Quasi-classical trajectory, Polarization-dependent generalized differential cross sections

摘要:
用准经典轨线方法在Aguado-Paniagua2(AP2)势能面上计算了反应物转动量子态对H+LiF→HF+Li反应立体动力学的影响. 给出了关于产物和反应物之间矢量相关的P(μr)和P(ár)的分布情况. 同时计算了四个极化微分反应截面. 结果表明转动量子态对H+LiF→HF+Li反应的矢量性质有很大影响. 还计算了H+LiF→HF+Li反应的反应几率.
