Abstract
Codeposition of $O_{2}$ with the superheated vapors, of sulfur from a Knudson cell yields a new isomer of $S_{2}O_{2}$ in which both the $S_{2}$ and $O_{2}$ moieties are retained. The two bands, 1408 end 726 $cm^{-1}$ are assigned to the 0-0 and S-S motions, respectively. Experiments with scrambled isotopes (O-16/O-18 and S-32/S-34) confirm the presence of the $S_{2}$ and $O_{2}$ fragments. In each case, a triplet of very narrow lines is obtained, suggesting that the vibrational coupling between the two fragments is minimal and/or that the two atoms in each fragment are equivalent. Upon phototosis $(\lambda > 200 nm)$, $S_{2}0$ and a perturbed (1347, 1147, and $519 cm^{-1}$) are obtained.
