✦ Synopsis

A kinetic study of the reactions of H atoms with CH,SH and C2H6SH has been carried out at 298 K by the discharge flow technique with EPR and mass spectrometric analysis of the species. The pressure was 1 torr. It was found: k1 = (2.20 * 0.20) x lo-'' for the reaction H + CH3SH (1) and k2 = (2.40 t 0.16) x lo-'' for the reaction H + C2H,SH (2). Units are cm3 molecule-' s-'. A mass spectrometric analysis of the reaction products and a computer simulation of the reacting systems have shown that reaction (1) proceeds through two mechanisms leading to the formation of CH3S + Hz (la) and CH3 + H,S (lb).

## Abstract Pulse radiolysis techniques were used to measure the gas phase UV absorption spectra of the title peroxy radicals over the range 215–340 nm. By scaling to σ(CH~3~O~2~)~240 nm~ = (4.24 ± 0.27) × 10^−18^, the following absorption cross sections were determined: σ(HO~2~)~240 nm~ = 1.29 ± 0
