Laser-induced fluorescence was used to detect CH3S radicals in the laser flash photolysis of CH3SH-O3-H2O-He(SF6) mixtures.Evidence was found for a reaction between CH3S and O3, with a rate coefficient (4.1+/-2.0)x10E-12 cm³ molecule_-1s_-1.The yield of CH3S from the reaction OH + CH3SH was determined to be 1.1+/-0.2.Our results suggest that the CH3S + O3 reaction could be the major sink for CH3S in the atmosphere.
