Rate constants for the vibrational dehyphen;excitation of CO(v=1) by NO, O2, and D2have been measured as a function of the temperature using the laserhyphen;induced vibrational fluorescence technique. In the temperature range from 100 to 700 K considered in our experiments, farhyphen;fromhyphen;resonance Vndash;V energy transfers occur between CO and the collision partners. In COndash;NO and COndash;O2samples, the CO fluorescence decay curves are single exponentials; only the total dehyphen;excitation rates khgr;COndash;M=kCOndash;M+kMCOof CO(v=1) by M=NO or O2may be experimentally deduced,kCOndash;Mbeing Vndash;V transfer rate andkCOMthe Vndash;TR dehyphen;excitation rate. In the COndash;D2system, the fluorescence exhibits a double exponential decay; the Vndash;V transfer ratekCOndash;D2is found to be much greater than the Vndash;TR dehyphen;excitation ratekCOD2, and the selfhyphen;relaxation ratekD2of deuterium has also been deduced from measurements. The Vndash;V transfer rateskCOndash;Mcalculated from a semiclassical method derived from that of Shin, and using a Morse potential, have been compared to the experimental results.
