Abstract: Gaseous CO in an Ar diluent is prepared in vibrational state $v = 1$ by absorption of pulsed CO laser radiation. Energy subsequently diffuses into higher vibrational states (to $v = 40$) by vibration-to-vibration exchange pumping. This diffusion of energy through vibrational quantum states is observed by step-scan FTIR emission spectroscopy on the 1st overtone CO bands. The method permits monitoring of the lime evolution of the vibrational state population, during the exchange pumping process. $\Delta \nu = 2$ emission spectra at 1 $cm^{-1}$ resolution and 50 $\mu sec$ time intervals are obtained, Vibrational state-resolved energy exchange rates are inferred from these measurements. In addition, state-resolved associative ionization rates for collisions of vibrationally excited. CO are inferred.
