## Abstract The reactions of groundβstate __S__(^3^__P__~__J__~) atoms with thiirane, methylthiirane, and __trans__β2,3βdimethylthiirane have been studied by flash photolysisβVUV kinetic absorption spectroscopy. From the analysis of the __S__(^3^__P__~__J__~) decay plots the following rate constant

β¦ Synopsis
The populations of the nascent CO formed in the reactions oi COS with 0(3P~) and O(" Dz) atoms: O? P) + cos s co? + so, O(' D) c COS 4 COi + SO have been determined by a CO laser resonant absorption method. The fraction of the total available energy channelled into CO as vibration ~1s calculated to be 11% in reaction (3) and only about 4% in (4). A simUar experiment for the O(' D) + CO? reaction showed no appteciabie CO production.
