โฆ Synopsis
A photoacoustic method is used under such experimental conditions that the (01'0) level ofC02 gas is not in e@li%rinrn with the other vibrational Ievck The rate mnsta.ntsk;o characterizing the CO2 (01'0) collisional deactivation by Nz, CO aad 02 are measured directly.

Collisional deactivation rate constants of CO+ A 'fI(v=O and 2) by He, Ne. Ar, N,, and CO have been determined by using a time-resolved laser-induced fluorescence technique. The results were combined with the previously determined Y= 1 rate constants to obtain an interesting u dependence of the rate
Vibration to vibration and rotation (WR) exchange occurs between CO and D, over the temperature range 340 K to 230 K, whilst at lower temperatures VT deactivation is dominant. Probabilities for these processes and for D, -D, deactivation are presented.
