Gas-phase ion chemistry of HP2-, FP2-, and HP2+

The gas-phase ion-molecule chemistry of the mass-selected ions HP2-, FP2-, and HP2+ has been studied in a tandem flowing afterglow selected-ion flow tube (FA-SIFT). Both HP2- and HP2+ are formed by direct electron impact on phosphine, followed by subsequent ion-phosphine reactions in the first flow tube. The related ion, FP2-, is formed via an ion-molecule reaction between HP2- and hexafluorobenzene. We have observed a number of reactions of HP2-, including hydride transfer and proton abstraction, as well as fluoride transfer and proton abstraction for FP2-. Using bracketing techniques, the gas-phase proton affinity of P2 has been determined as 162 ± 3 kcal mol-1, in good agreement with Nguyen and Fitzpatrick's theoretically predicted value of 158 ± 3 kcal mol-1. The heats of formation of HP2-, HP2+, HPPH, FP2-, and FPPH have been estimated from the experimentally determined hydride, proton and fluoride affinities of P2 and from the gas-phase acidities of HPPH and FPPH.

Ion-Molecule Reactions Involving H3O+, H2O+, and OH+ at Thermal Energy

The rate coefficients for a variety of reactions involving OH+, H2O+, and H3O+ with CS2, H2S, SO2, NO, NO2, N2O, N2, O2, CH4, CO2, CO, NH3, and H2 are obtained with a selected ion flow tube.The product channels include proton transfer, charge transfer, atom abstraction, and association.Most of the reaction rates are fast and have high reaction efficiencies.Reaction of OH+ with NO2 is found to produce both NO2+ and NO+; even though both reaction channels are also exothermic with H2O+, only NO2+ is produced.H3O+ is found to undergo association reactions with SO2 and N2O and H2O+ does so with CO2 and N2O.The reaction of H2O+ with N2O also involves a second-order process in addition to the association pathway.
