Measurement of the rate constant for the NO+HO2 yields OH+NO2 reaction using laser magnetic resonance
Technical Report

OSTI ID:5503484
The rate constant of the gas phase reaction NO + HO2 yields NO2 + OH was measured in an isothermal discharge - flow system at 296 K and at pressures around 700 (Pa). The concentration profiles of OH- and HO2 radicals were measured directly with a laser-magnetic resonance spectrometer. The reaction H + O2 + M yields HO2 + M with He as the main carrier gas was used as the HO2-source. In all experiments NO was in large excess over HO2. The rate constant of the wall reactions of OH and HO2 were determined in separate experiments. The rate constant of the first reaction is found to be Kl (296K) = (3.5 + or = 1) tera (cu cm/molsec). Previous measurements described in the literature are discussed.
