Notes:
The radiative lifetimes of the v(triple-prime)3 = 0–2 levels of the CH3S (A˜ 2A1) radical have been determined by means of the laser-induced fluorescence technique. CH3S was generated by either laser photolysis of CH3SSCH3 (both in cell and in supersonic expansion) or the reaction of F and CH3SH in a discharge-flow system. The radiative lifetimes for v(triple-prime)3 = 0, 1, and 2 levels are 1105±25, 910±20, and 250±10 ns, respectively, greater than previously reported values. The rate coefficients for the v(triple-prime)3 = 0, 1, and 2 levels for quenching by CH3SSCH3 have also been determined to be 7.8, 7.8, and 16.5×10−10 cm3 molecule−1 s−1, respectively.
