Abstract

We present quasiclassical trajectory analysis of O2+ O collisions at conditions representative of a crossed molecular beam experiment. These calculations are compared to experimental data in order to further validate the Potential Energy Surfaces (PESs) recently developed at the University of Minnesota. There are nine possible degenerate combinations of spin and spatial state for O2+O, each with its own PES. Analysis is performed on the combined nine state system and on each state separately. We show that using nine surfaces to account for all possible states improves agreement with experiment for both inelastic and exchange collisions. Trends seen in the scattering angle and translational energy distributions are interpreted in terms of energy barriers to exchange and opacity functions for each state. Further analysis of energy transfer in exchange collisions is performed for the aggregated nine state system and shows different results than single state analysis in other work.
