and 2.6x10(-11) exp(285+/-20)/T(K)} cm3 molecule-1 s-1, respectively. SH(SD) radicals were generated by pulsed laser photolysis of H2S(D2S) or CH3SH and detected via pulsed laser-induced fluorescence. The laser-induced fluorescence excitation spectrum of SH was found to be contaminated by the presence of the SO radical. This contamination is suggested as a possible reason for differences among some

SD反应的速率常数分别为2.8 x 10(-11)exp (270 +/- 40)/ T(K)}和2.6x10(-11) exp (285 +/- 20)/ T(K)} cm3分子-1 s-1。SH(
SD)自由基是由
H2S(D2S)或CH3SH的脉冲激光光解产生的,并通过脉冲激光诱导的荧光进行检测。发现SH的激光诱导的荧光激发光谱被SO自由基的存在所污染。建议将该污染作为文献中某些报道的k1值之间差异的可能原因。当 大于100 pptv时,标题反应会影响SH自由基的大气寿命,但k1的修正值不会显着改变我们目前对大气中SH氧化的理解。
