“…As a kind of highly reactive sulfur compound, CH 3 SH (methanethiol or methyl mercaptan) has been drawing long‐term attention because of its critical role in the atmospheric sulfur cycle . Significant amount of recent studies have focused on the reactions of CH 3 SH with series of species, such as H, O( 3 P), S( 3 P), OH, NO x (x = 1, 2, 3), X(X = F, Cl, Br), CN, XO(X = Br, I), O 3 , HOCl, CH 3 SLi, H 2 O 2 , HOO, and so on.…”
