Comments: 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 the percent change in absorption upon cooling to 
195°K. The structured features in the absorption are reinvestigated and discussed.
