The atmospherically highly relevant methylsulfinyl radical CH3(O)S was generated thermally under flash pyrolysis conditions and isolated in Ar matrices at 10 K; the allyl radical is a byproduct. CH3(O)S and its D3- and (13)C-isotopologues were characterized through the excellent agreement between experimental and computed IR and UV/Vis spectra.

less stable than sulfine, in marked contrast to the isomer energy difference of dioxirane vs carbonyloxide (ca. -25 kcal mol(-1)). This is due to the strong positive polarization (blue potential) versus the highly electronegative oxygen atom (red). The stability ordering and the relative energy differences of carbonyl versus thiocarbonyl groups underline the likely role oxathiiranes play in sulfur
