Abstract: 
When mixing SO with O-2 in N-2, 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 SO3 and 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 of (OS)-O-16-(OO)-O-18-O-18 yields a ca. 2:1 mixture of cyclic (OS)-O-18(=O-16)O-18 and (OS)-O-16(=O-18)O-18. The characterization of OS-OO and OS(=O)O with IR and UV/Vis spectroscopy is supported by high-level ab initio computations.
