VIBRATIONAL-STATE DEPENDENCE OF THE N-2(-3)+HCL REACTION AT THERMAL ENERGIES()(V=0)

N-2(+)(upsilon = 0-3) + HCl reaction rate constant is studied at therm al energies. The rate constants for upsilon = 0, 1, 2, and 3 are 5.3(/-1.6) X 10(-10), 8.3(+/-2.5) X 10(-10), 7.9(+/-2.4) X 10(-10), and 8. 0(+/-2.4) X 10(-10) cm(3) molecule(-1) s(-1), respectively, showing li ttle or no dependence on vibrational excitation. Vibrational deactivat ion of the N-2(+) is at most 20% of the total removal rate. The branch ing ratio for the charge transfer channel to the hydrogen transfer cha nnel is also not altered significantly by N-2(+) vibrational excitatio n. (C) 1997 Elsevier Science B.V.
