摘要: Quasi-classical trajectory (QCT) calculations are employed to study the dynamic properties for \mbox{H(D)} + \mbox{OF} reactions on the adiabatic potential energy surface (PES) of the \mbox{1}{ }^{3}\mbox{A}'' triplet state. Obvious differences between the reaction probabilities for J = 0, integral cross sections for J \ne 0, branch ratios of the product and internuclear distances as well as product rotational alignments between the title reactions are found. These differences are attributed mainly to the different reduced masses of the reactants and the different zero-point energies (ZPEs) of the transition state.

Abstract: Quasi-classical trajectory (QCT) calculations are employed to study the dynamic properties for H(D) + OF reactions on the adiabatic potential energy surface (PES) of the 1$^{3}$A$''$ triplet state. Obvious differences between the reaction probabilities for $J = 0$, integral cross sections for $J \ne 0$, branch ratios of the product and internuclear distances as well as product rotational alignments between the title reactions are found. These differences are attributed mainly to the different reduced masses of the reactants and the different zero-point energies (ZPEs) of the transition state.

Key words: isotope effects, H(D)+OF reactions, quasi-classical trajectory
