Vibrational relasatioo of CO2 by Hz0 has been studied theoretiully. Earlier theoretical works are critically analyzed. A new mechanism of V-R-T interaction is put forxvard and a functional equation for the probability factor is obtained. Collisions of CO2 with H-J 0 adsorbed on a solid surface are

Probabilities for the (VT) and (VR) deactivation of CO have been calculated from relaxation times measured down to 77 K using laser fluorescence. Only in the case of deactivation by p-H2 is the (VR) process important; its rate exceeds that for (VT) deactivation between 320 K and 110 K.
## Rate constants for the deacrivarion of N,(u= 1) by n-H, and by PHI between 300 and 80 K have ken measured using laser fluorescence from CO(u= 1). There is no n-HZ/p-Hz difference. N,(v=l) is deactivated about 3 times more slowly than is CO(u = 1). Comparison with results in liquid N, support t
