FTIR studies of O((super 3)P) atom reactions with CSe(sub 2), SCSe, and OCSe

The overall rate coefficients of the reactions of CSe(sub 2), SCSe, and OCSe with O((super 3)P) atom are examined. An excellent match between the decay rate of OCSe with the appearance rate of CO upon O atom reactions is found, which suggest that only a single channel is open while the measured rate coefficient may be used to describe the single reaction, O + OCSe -> CO +SeO.
