✦ Synopsis

A tandem quadrupole mass spectrometer is used to study the charge transfer reactions NH: + NO and NO+ + NH, over a collision energy range 1.5-l 3 eV. The vibrational state of the reagent ions is selected by resonance-enhanced multiphoton ionization. For the 0.9 eV exothermic process NHf +NO+NH,+NO+ excitation of the u2 umbrella bending mode ( vz=O-12) causes no marked change in the charge transfer cross section, while in the reverse process NO+ +NH,+NO+NH: excitation of the NO+ vibration (v= O-6) strongly enhanced the charge transfer cross section.

The rate constant for the NH 3 ϩ NO 2 L NH 2 ϩ HONO reaction (1) has been kinetically modeled by using the photometrically measured NO 2 decay rates available in the literature. The rates of NO 2 decay were found to be strongly dependent on reaction (1) and, to a significant extent, on the secondary
