✦ Synopsis

The kinetics of the gas phase reaction of OH radicals with dimethyl sulfide (CH,SCH,) have been studied a t various temperatures and total pressures using two relative rate methods and a flash photolysis technique. For the relative rate methods, rate constants were measured at 296 L 2 K as a function of the O2 pressure at a total pressure of ca. 740 torr. Data from these three experimental techniques were not in agreement. It is concluded that the relative rate techniques are subject to secondary reactions, possibly involving CH3S radicals. A rate constant of(2.5 Tt:) x lo-" e"30-102"T cm3 molecule-' s obtained using the flash photolysis-resonance fluorescence data in the absence of 02, and which is in agreement with the lower range of values previously reported in the literature, is recommended.
