title: Quenching of Infrared Chemiluminescence. 1: The Rates of De-Excitation of CO (4 </= v </= 13) by He, CO, NO, N(2), O(2), OCS, N(2)O, and CO(2).
abstract: Infrared chemiluminescence has been observed from vibrationally excited CO, formed in the reaction, O + CS ? CO + S. The quenching of the CO overtone spectrum has been studied as a function of the concentration of each of a number of added gases. A steady-state treatment is developed which allows rates to be determined for the de-excitation of individual vibrational levels of CO (4 </= nu </= 13) by He, CO (nu = 0), NO, N(2), O(2), OCS, N(2)O, and CO(2). The experimental results are compared with theoretically predicted rates. Finally, the importance of the results for interpreting the behavior of CO vibrational lasers is considered.
