When mixing SO with O₂in N₂, Ne, or Ar, an end-on complex OS–OO forms in the gas phase and can subsequently be trapped at cryogenic temperatures (2.8–15.0 K). Upon infrared light irradiation, OS–OO converts to SO₃and SO₂+ O with the concomitant formation of a rare 1,2,3-dioxathiirane 2-oxide,i.e., cyclic OS(O)O. Unexpectedly, the ring-closure of¹⁶OS–¹⁸O¹⁸O yields aca.2 : 1 mixture of cyclic¹⁸OS(¹⁶O)¹⁸O and¹⁶OS(¹⁸O)¹⁸O. The characterization of OS–OO and OS(O)O with IR and UV/Vis spectroscopy is supported by high-levelab initiocomputations.
