Kinetics of the CN+OCS reaction

The CN+OCS reaction was studied using flash photolysis/time-resolved infrared laser spectroscopy. The reaction is fast, with a rate constant of (9.75±0.5)×10−11 cm3 molecule−1 s−1 at 296 K and 2.2 Torr pressure. Detection of CO products indicates that the CO+NCS product channel dominates this reaction, and that the CO is produced vibrationally cold, with >98% in the vibrational ground state.
