Abstract

Rate constants for the charge-transfer reaction N2+(V)+ Ar>N2+Ar+ are measured at thermal energies as a function of initial vibrational excitation by laser-induced fluorescence. The reaction is slow for v=0, whereas the rate constants for v=1-4 are large (approximately equal to} 0.5 Langevin rate) and show little vibrational dependence. The rate constants are quantitatively described by a simple model based on energy resonance and a set of modified Franck-Condon factors, which take into account the change in vibrational wave functions of N2+ and N2 at short (N2-Ar)+ distances.
