ON THE DYNAMICS OF THE SELECTIVE ELECTRONIC AND VIBRATIONAL-EXCITATION OF NITROGEN IN THE RECOMBINATION BETWEEN F- AND N-2(+)

The charge transfer reaction F-(S-1(0))+N-2(+)(X (2) Sigma(g)(+))-->N- 2(B (3) Pi(g), v)+F(P-2) is analyzed by numerical calculations of the dynamics on empirical covalent and ionic potential energy surfaces, Th e present calculations are aimed at an explanation of the branching ra tios between the vibrational levels of the N-2(B) product as previousl y measured. The collisions are treated as sudden with respect to molec ular rotation and the reaction is assumed to be adiabatic on vibronic states. Crossings between entrance and exit channels, which are respon sible for the nonadiabatic transitions, are treated by Landau-Zener th eory and information on the strength and radial dependence of the rele vant coupling matrix element is obtained.
