Abstract
The absorption spectra of the vapors of $S^{16}O_{2}$ and $S^{18}O_{2}$ have been reexamined in the neighborhood of 2300 \AA. The interpretation 2$\nu^{\prime}_{s} = 560 cm^{-1}$ is confirmed by the fact that it leads to an explanation of the isotope shift of the (0-0) band. A double minimum potential in the $Q^{\prime}_{3}$ mode is determined. Accurately measured hot bands yield information about ground state frequencies which is not available from infra-red data.
