摘要

First accurate quantum mechanical scattering calculations have been carried out for the S (P3) +OH (X Π2) →SO (X 3 -) +H (S2) reaction using a recent ab initio potential energy surface for the ground electronic state, X A2 ″, of HSO. Total and state-to-state reaction probabilities for a total angular momentum J=0 have been determined for collision energies up to 0.5 eV. A rate constant has been calculated by means of the J -shifting approach in the 10-400 K temperature range. Vibrational and rotational product distributions show no specific behavior and are consistent with a mixture of direct and indirect reaction mechanisms.
