Abstract: | The atmospheric reaction of the methylthiyl radical (CH3S) with O3 was investigated as a function of temperature (259–381 K), in the pressure range of 25–300 Torr, using the technique of laser photolysis/laser-induced fluorescence. The resulting Arrhenius expression, with an uncertainty of ±2σ, was k1(T=259–381 K)=(1.02±0.30)×10−12 exp[(432±77) K/T] cm3 molecule−1 s−1. The obtained rate constant k1 was independent of pressure over the limited range employed. Our results are compared with the previous studies carried out, at single temperature and as a function of temperature, by different techniques. |
