Methanesulfonic acid (MSA) and SO<sub>3</sub> formation from the addition channel of atmospheric dimethyl sulfide oxidation
The formation of methanesulfonic acid (MSA) from the dimethyl sulfide addition channel primarily proceeds <i>via</i> the reaction of methylsulfonyloxy radicals (CH<sub>3</sub>SO<sub>3</sub>) with H-atom donors, other than HO<sub>2</sub> radicals. In competition with it, thermal decomposition of CH<sub>3</sub>SO<sub>3</sub> results in SO<sub>3</sub> generation. The MSA/SO<sub>3</sub> ratio is driven by the temperature dependence of CH<sub>3</sub>SO<sub>3</sub> decomposition.
