Kinetics of the reaction of methyl radicals with nitrogen dioxide

The mechanism of the reaction CH3 + NO2→CH3O + NO was studied and its rate constant at 295 K was determined to be (2.5 ± 0.5) × 10−11 cm3 molecule−1 s−1 Methyl radicals were produced in a tubular reactor by IR multiphoton dissociation of C6F5OCH3, and concentration profiles were measured using photoionization mass spectrometry.
