State-to-state vibrational rate coefficients for the collision of two vibrationally excited nitrogen molecules have been calculated using quasiclassical trajectories and networked computing. For this purpose two potential energy surfaces formulated using completely different interaction models have been used. The differences in the calculated rates have been rationalized in terms of the dependence of quasi-resonant transition probabilities on the collision energy and the impact parameter. The effect of the different long-range interaction on the calculated scattering properties is discussed. (C) 2014 Elsevier B.V. All rights reserved.
