Abstract

In the present work, implementation of different binning approaches in the quasi classical trajectory study of N2-N2 state resolved relaxation is studied. A new, two-dimensional binning approach based on the rotational and vibrational energies is introduced to improve the binning approach used in our earlier work1, 2 that was based only on internal energy. New relaxation cross sections are computed and compared with those obtained in our earlier work. Binning sensitivity studies in nonequilibrium relaxation cases shows that bins with small rotational or vibrational energy levels spacing and selection of post-collision internal energies from a Boltzmann distribution are needed to equilibrate the system in the final steady state.
