The dependences of the effective binary rate coefficient, k eff , for the reactions of Xe + and O 2 + with CH 3 CN were studied by the SIFDT method over in wide ranges of translational energy and buffer gas pressure. The energy dependences indicate a

A detailed kinetic study for the production of secondary and ternary ions in O 2 + (Xe + )–CH 3 CN systems was made by applying the SIFDT techniques. “Nonprotonated complexes” (cation radical dimers or higher aggregates) of acetonitrile were pr

A selected ion flow drift tube (SIFDT) has been used to measure vibrational quenching rate constants of HCN+ and DCN+ in collisions with He from 0.05 to 0.35 eV mean relative kinetic energy. The measured quenching rate constants fit linear Landau–T

The mechanism for isomerization of HCN+ ions to the more stable HNC+ in collision with CO2 at thermal energy has been confirmed to be a double proton transfer in the collision complex. First a proton is transferred from C in HCN+, then, following CN

The very fast charge transfer of N+2 with SF6 and the H abstraction from H2 by N+2 are found not to be detectably diminished by vibrational excitation of N+2 to ν=1. No vibrational quenching was observed in either case, establishing an upper limit o

The reactivity of HCN + and HNC + has recently been studied in a selected-ion flow tube. The astrophysical significance of differences in HCN + /HNC + production and reactivity is discussed. In interstellar clouds, equal amounts of HCN + and HNC + ar

Rate constants for the reaction of the two isomers of protonated N 2 O, HNNO + and NNOH + , with CH 4 and NO have been measured as a function of relative kinetic energy. The CH 4 measurements allow a determination of the proton affinity of N 2 O on N

The reactions of HBr+ with CF4, NO, CO2, CH4, N2O, SO2, COS, H2S and SF6 have been studied in a SIFDT apparatus. For some reactions the variation of rate constant with centre of mass collision energy Ecm has been investigated. The rate constant for t

In the course of mechanistic studies on HCN+ isomerization in reaction with CO and CO2, we have fortuitously determined the heats of formation of HNC and HNC+ with good precision. The uncertainty is the uncertainty in the heat of formation of HCN, ±
