摘　　要：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） cm^3/（molecule.s）. A compared investigation of the reaction between ozone and ethene had a kC2H4 value of （1.35 ± 0.11） × 10^-18 cm^3/（molecule.s） at room temperature.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.
