Abstract: In this work we present a molecular level study of N2+N collisions, focusing on excitation of internal energy modes and non-equilibrium dissociation. The computation technique used here is the direct molecular simulation (DMS) method and the molecular interactions have been modeled using an ab-initio potential energy surface (PES) developed at NASA’s Ames Research Center. We carried out vibrational excitation calculations between 5000K and 30000K and found that the characteristic vibrational …
