Abstract
The single-electron transfer reaction between NO2+ and NO, which initially forms a pair of NO+ ions, has been studied using a position-sensitive coincidence technique. The reactivity in this class of collision system, which involves the interaction of a dication with its neutral precursor, provides a sensitive test of recent ideas concerning electronic state selectivity in dicationic single-electron transfer reactions. In stark contrast to the recently observed single-electron transfer reactivity in the analogous CO22+/CO2 and O-2(2+)/O-2 collision systems, electron transfer between NO2+ and NO generates two product NO+ ions which behave in an identical manner, whether the ions are formed from NO2+ or NO. This observed behaviour is in excellent accord with the recently proposed rationalization of the state selectivity in dication-molecule SET reactions using simple propensity rules involving one-electron transitions.
