Abstract
Rate constants for the quenching of O2(1∑+ g) by hydrogen have been measured between 173 and 393 K. The rate constants can be represented by the Arrhenius equation k= 3.09 × 109 exp (–1110/RT) dm3 mol–1 s–1 over this temperature range. Contributions from two different quenching mechanisms have been calculated. The largest contribution to the quenching rate in this temperature range has been found to be due to the interaction of the transition quadrupoles of O2 and H2. Short range interactions appear to make a smaller contribution to the quenching reaction. The combination of both these quenching mechanisms yields rate constants which agree well with the experimental results.Keywords
