The reaction of OH radicals with CS 2 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 O 2 present in the system. The products of the reaction were found to be COS and SO 2 with one molecule of each being formed for every reacted CS 2 . A value of (2.7 ± 0.6) × 10 −12 cm 3 /molecule·s was obtained as effective rate constant for the reaction at 293 K in 760 torr of synthetic air.
