摘要: Quasi-classical trajectory (QCT) studies on the stereodynamics of H + BrO→O + HBr reaction have been performed on the X1A' state of ab initio potential energy surface by Peterson [Peterson K A 2000 J. Chem. Phys. 113 4598] in a collision energy range from 0 kcal/mol to 6 kcal/mol. Two of the polarization-dependent generalized differential cross sections (PDDCSs), (2π/σ)(dσ00/dωt) (PDDCS00) and (2π/σ)(dσ20/dωt) (PDDCS20) are considered. The rotational polarizations of these products show sensitive behaviors to the calculated collision energy range. Furthermore, in order to gain more knowledge about vector correlations, the product angular distribution, Pr), and the dihedral angle, Pr), are calculated, and the results indicate that both the rotational alignment and orientation of the product are enhanced as collision energy increases.
