Scientific paper

The reactions of O2(+).O2 ions with the minor stratospheric neutrals CO2, O3, and CH4 have been studied in a variable-temperature flowing afterglow to test whether they represent reactions paths that can compete with the one leading to H3O(+).nH2O ions and hence can offer the possibility of different terminal ions. The reaction of O2(+).O2 with CH4 was found to be too slow to be competitive. The measured equilibrium constants of the reactions with CO2 and O3 indicated that only the latter, which had an O2(+).03 product, could play a stratospheric role. The O2(+).O3 ion chemistry was also examined. It was found that the reaction with CH4 was immeasurably slow but that the reaction with H2O was fast, yielding O2(+).H2O ions. Since this product ion is part of the sequence of reactions that lead to the H3O(+).nH2O ions, it is concluded that CO2, O3, and CH4 do not afford alternative reaction paths that could rationalize the recent in situ observation of non-H3O(+).nH2O ions in the lower stratosphere.
