    The pulse radiolysis of SF6/CH3SCH3/O-2/NO2 gas mixtures was used to generate CH3SCH2O2 radicals in the presence of NO2. By monitoring the rate of NO2 decay using its absorption at 400 nm, rate constants for the reaction of CH3SCH2O2 radicals with NO2 were measured to be (9.2 +/- 0.9) x 10(-12) and (7.1 +/- 0.9) X 10(-12) cm(3) molecule(-1) s(-1) at room temperature in 1000 and 300 mbar of SF6 diluent, respectively. Results are discussed with respect to the atmospheric chemistry of dimethyl sulfide.
