Quasi-Classical Trajectory Studies of the Insertion Reactions S(1D) + H2, HD, and D2

Abstract

In this work, we present the results of a quasi-classical trajectory (QCT) calculation using a newly developed potential energy surface for the title reactions. The integral cross sections, the product state-resolved differential cross sections, the angle-state-specific energy partitions, and other relevant reaction attributes are computed. The QCT integral cross sections, the differential cross sections, and the gross features of the product distributions are consistent with a simple view of the reaction as mediated by capture dynamics in the entrance channel, followed by the statistical decay of a long-lived complex. We present a comparison to the molecular beam experiments of Lee and Liu, which show agreement in the broad pattern of results but also exhibit significant differences in the more finely resolved quantities.
