Abstract
The pulse radiolysis of SF6/CH3SCH3/O-2/NO2 gas mixtures was used to g enerate CH3SCH2O2 radicals in the presence of NO2. By monitoring the r ate of NO2 decay using its absorption at 400 nm, rate constants for th e 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) a t room temperature in 1000 and 300 mbar of SF6 diluent, respectively. Results are discussed with respect to the atmospheric chemistry of dim ethyl sulfide.
