Reaction rate constants for O2-(H2O)n ions n=0 to 4, with O3, NO, SO2, and CO2

Article abstract of DOI:10.1063/1.443220

Reaction rate constants for O2^-(H2O)n ions with n=0 to 4 have been measured in a variable temperature flowing afterglow apparatus with a novel ion source configuration.The ios have been reacted with O3, NO, SO2, and CO2.The reaction with O3 is charge-transfer to produce O3^- with simultaneous transfer of water ligands.The reactions with NO and SO2 are ligand switching reactions in which NO or SO2 displaces one or more water molecules clustered to O2^- leaving NO3^- and SO4^- as core ions.In these cases, the reaction rate constants are not decreased measurably by an increase in n.CO2 rapidly displaces H2O in reaction with O2^-(H2O) but does not react with O2^-(H2O)3,4.Isotopically labelled O2^- ions were used to elucidate several reaction mechanisms.The rapid destruction of O2^-(H2O)4 ions by O3, NO, and SO2 insure that O2^-(H2O)n ions cannot be dominant small air ions in the earth's lower atmosphere.
