The reaction of SH radical with N2O was investigated by using two complementary experimental methods: (a) a pulsed photolysis apparatus where SH was detected via laser-induced fluorescence and (b) a discharge flow tube where SH was detected via chemical ionization mass spectrometry. The rate coefficient for this reaction, k(1), was found to be less than 5 x 10(-16) cm(3) molecule(-1) s(-1) at 298 K, in contrast to the large value reported in the literature [Ravichandran; et al. Chem. Phys. Lett. 1994, 217, 375-379]. Secondary reactions were deduced to be unimportant in our system. Some possible reasons for the previously reported high value are presented. The low value of k(1) makes the oxidation of SH by N2O and removal of N2O by SH unimportant in the earth's atmosphere.
