Rate Coefficients and Product Ion Distributions for Reactions of CO2 · CO2+ Ions with Neutral Molecules at 300 K

Abstract Reactions of CO2 · CO2+ ions with CO, N2O, CH4, H2O, O2, COS, C2H2, C2H4, C3H6, NH3, CH3NH2, and NO have been studied using a drift tube mass spectrometer with selected ion injection. In most cases, the major reaction channel is charge transfer. Molecular displacement (switching) occurs also in several cases. In general, the measured rate coefficients agree with those calculated from Langevin or ADO theory. Two exceptions are the reactions with methylamine and nitric oxide where the rate coefficients are smaller by two orders of magnitude.
