The products of the reaction of OH with CH 3 SSCH 3 (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 CH 3 S and CH 3 SOH are produced in the title reaction. The latter apparatus was used to quantify the yield of CH 3 S in the title reaction. The measured yield was 0.28 ± 0.20, independent of pressure and buffer gas, suggesting that products other than CH 3 S and CH 3 SOH are also important in this reaction. The quoted uncertainty is at the 95% confidence level and includes estimated systematic errors. © John Wiley & Sons, Inc.
