✦ Synopsis

The reaction of OH radicals with CS2 has been investigated by the application of Fourier transform infrared spectroscopy using both photolytic and nonphotolytic competitive techniques in a 420-L reaction chamber at different pressures over the temperature range of 264-293 K. The measured effective rate constant was found to be dependent on total pressure, temperature, and the mole fraction of 0 2 present in the system. The products of the reaction were found to be COS and SO2 with one molecule of each being formed for every reacted CS2.

A value of (2.7 f 0.6) X cm3/molecule.s was obtained as effective rate constant for the reaction at 293 K in 760 torr of synthetic air.
