Atmospheric chemistry of dimethyl sulfide. Kinetics of the CH3SCH2O2+ NO2reaction in the gas phase at 296 K

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

The pulse radiolysis of SF6/CH3SCH3/O2/NO2gas mixtures was used to generate CH3SCH2O2radicals in the presence of NO2. By monitoring the rate of NO2decay using its absorption at 400 nm, rate constants for the reaction of CH3SCH2O2radicals with NO2were measured to be (9.2 ± 0.9) × 10-12and (7.1 ± 0.9) × 10-12cm3molecule-1s-1at room temperature in 1000 and 300 mbar of SF6diluent, respectively. Results are discussed with respect to the atmospheric chemistry of dimethyl sulfide.
