The HS and HSO radicals are of interest because they play important roles in the H2S oxidation processes that may contribute to the production of atmospheric H2S04. HS is known to be the product of the well-characterized reaction of H2S and OH.'* 2 The subsequent oxidation of HS by N023-5 or 035-7 leads to HSO production. There are two published reports of the rate constant for reaction I. Friedl et aL8 measured k,=(3.2 f 1.0) X
