Abstract
Rapid rates for vibrational energy transfer at room temperature have been observed for energy transfer from the CO(v=1) to the coupled O3(200), O3(101), and O3(002) levels. Very rapid transfer also occurs from the coupled O3(001) and O3(100) levels to the OCS(020) level. The measured rates are compared with results calculated with the first order perturbation theory of dipole transition–moment interactions. A measurement of the V→T deactivation of the bending mode of OCS gives a rate constant of (3.4±0.4) ×103 sec−1 Torr−1 at 298 °K. Values are also given for the deactivation of OCS(001) by N2 and for the V→T deactivation of OCS by Ar.Keywords
