Radiative lifetimes for CH3S(Atilde;thinsp;2A1) in the ugr;3=0, 1, and 2 levels are 760plusmn;60, 810plusmn;60, and 197plusmn;15 ns, respectively. These results are in disagreement with previous work on the ugr;rsquo;3=0 and 1 levels although in agreement for the ugr;3=2 level. Since the previous work was in a beam, it is possible that loss from the viewing region contributed to the shorter lifetimes reported previously for the lower levels. Quenching by (CH3S)2is fast for all three levels.
