Vibrational state dependence of the N2+(v=0–3) + HCl reaction at thermal energies

N2+(v=0–3) + HCl reaction rate constant is studied at thermal energies. The rate constants for v=0, 1, 2, and 3 are 5.3(±1.6)×10−10, 8.3(±2.5)×10−10, 7.9(±2.4)×10−10, and 8.0(±2.4)×10−10 cm3 molecule−1 s−1, respectively, showing little or no dependence on vibrational excitation. Vibrational deactivation of the N2+ is at most 20% of the total removal rate. The branching ratio for the charge transfer channel to the hydrogen transfer channel is also not altered significantly by N2+ vibrational excitation.
