A continuum source with three different interference filters and two different monochromatic sources were used to photolyze OCS in the region from 200 nm to 300 nm. The total quantum yield for the production of CO was measured, and the results indicate a primary quantum yield of 0.72¿0.08. Absorption cross sections for OCS measured at 0.5-nm intervals are reported as well as te prercent change in absorption upon cooling to 195¿K. The structured features in the absorption are reinvestigated and discussed.
