Effects on the chemical stereodynamics of the initial vibrational excitation in the F + LiH (v = 0-2, j = 0) → LiH + H reaction

摘要

In this work, the product polarization characteristics are reported for the reaction F + LiH (v = 0 - 2, j = 0) → LiF + H at the collision energy of 35 kcal/mol, by using the QCT method on the AguadoPaniagua-potential energy surface (see Aguado et al.). The distribution of P(θ _r) which represents the K (reagent relative velocity vector) and J′ (product rotational angular momentum vector) correlation, the dihedral angle distribution of K-K′ (product relative velocity vector)-J′ P(φ _r), the angular distribution P(θ _r, φ _r) and the four polarization-dependent differential cross sections (2π/σ) (dσ _(00)/dω _t), (2π/σ) (dσ _(20)/dω _t), (2π/σ) (dσ _(22+)/dω _t), (2π/σ)(dσ _(21-)/dω _t) in each initial state are presented and discussed.
