Abstract

This paper explores nonequilibrium dissociation and internal energy excitation of molecular oxygen due to O2 + O and O2 + O2 interactions using direct molecular simulation. The O2 + O interactions were modeled using a suite of nine potential energy surfaces proposed by Varga et al. [1] corresponding to O2 + O interactions in the ground electronic state of the interaction partners. O2 + O2 interactions were modeled using three potential energy surfaces proposed by Paukku et al. [2, 3]. Good agreement between experimental data in the literature and computational data presented in this study for vibrational excitation and dissociation due to O2 + O and O2 + O2 interactions is found.
