Absolute rate constants for the reaction of ozone with dimethyl sulfide (DMS) were measured in a 200-L Teflon chamber over the temperature range of 283–353 K. Measurements were carried out using DMS in large excess over ozone of 10 to 1 or greater. Over the indicated temperature range, the data could be fit to the simple Arrhenius expression as kDMS=(9.96±3.61)×10-11 exp[(7309.7±1098.2)/T] cm3/(molecule·s). A compared investigation of the reaction between ozone and ethene had a kC2H4 value of (1.35±0.11)×10-18 cm3/(molecule·s) at room temperature.
