✦ Synopsis

The products of the reaction of OH with CHsSSCH3 (DMDS) were investigated at 298 K using a flow tube reactor coupled to a photoionization mass spectrometer and a pulsed photolysis-pulsed laser induced fluorescence apparatus. The results from the former apparatus were semi-quantitative and showed that CH3S and CHsSOH are produced in the title reaction. The latter apparatus was used to quantify the yield of CH3S in the title reaction. The measured yield was 0.28 ? 0.20, independent of pressure and buffer gas, suggesting that products other than CHsS and CHsSOH are also important in this reaction. The quoted uncertainty is at the 95% confidence level and includes estimated systematic errors.

## Abstract We study dynamics of the CH~3~ + OH reaction over the temperature range of 300–2500 K using a quasiclassical method for the potential energy composed of explicit forms of short‐range and long‐range interactions. The explicit potential energy used in the study gives minimum energy paths
