N2 - The mechanism of the reaction between H and CH3NO2, has been studied in a discharge flow system using electron paramagnetic resonance and modulated molecular beam mass spectrometry for the detection of reactants and products. Deuterium atoms have, in addition to CD3NO2, been used to support the proposed reaction mechanism. The reaction was studied with the atomic reactant in slight excess at 298 K and a total pressure of 2 Torr. Two concurrent reaction channels: (1a) H+CH3NO2→HONO+{radical dot}CH3 and (1b) H+CH3NO2→CH3NO+{radical dot}OH were observed. The branching ratio, k1a/(k1a+k1b), is 0.7±0.2.
