Abstract: 

The atmospherically highly relevant methylsulfinyl radical (CH₃(O)S˙) readily reacts with molecular triplet oxygen in cryogenic argon matrices containing small amounts of ³O₂. Comparison of experimental and computed IR- and UV/Vis spectra, including isotope exchange, show that the initially formed ³O₂ adduct has the structure of a peroxyl radical (CH₃(O)SOO˙), which upon irradiation with UV light isomerizes to the methylsulfonoxyl radical (CH₃SO₃˙). The latter transforms into the methansulfonic acid radical (˙CH₂SO₃H) by irradiation with visible light. During the matrix photolysis small amounts of SO₃ and the methyl radical were detected indicating competitive direct photodissociation.
