The atmospherically important reactions of both CH3S and CH3SOO were examined using the technique of pulsed laser photolysis/laser-induced fluorescence.Rate coefficients for the reactions CH3S + O3 -> products (1) and CH3S + NO2 -> CH3SO + NO (2) were measured to be k1(T) = (1.98 +/- 0.38) x 10-12 exp cm3 molecule-1 s-1 and k2(T) = (2.06 +/- 0.44) x 10-11 exp cm3 molecule-1 s-1.The reactions of the weakly bound CH3SOO adduct with O3, NO2, and NO were studied at low temperatures.The rate coefficients for the adduct reactions are as follows: CH3SOO + O3 -> products (4), k4 -13 cm3 molecule-1 s-1 at T = 227 K; CH3SOO + NO2 -> products (5), k5 = (2.2 +/- 0.6) x 10-11 cm3 molecule-1 s-1 at T = 227-246 K; and CH3SOO + NO -> products (6), k6 = (1.1 +/- 0.4) x 10-11 cm3 molecule-1 s-1 from T = 227-256 K.The measured values of k5 and k6 were independent of temperature and pressure over the limited ranges employed.The atmospheric implications of these findings are discussed.
