✦ Synopsis

The vibrationaI energy relaxation rates of the liquid nitrogen-CO system have been measured by optically pumping the collision-induced fundamentalvibrational absorption band of liquid Nz with the output of an HBr TEA laser. A rad2atively dominated value of 56 f 10 s is found for the intrinsic nitrogen relaxation time. The CO contribution to the decay rate is explained on the basis of a simple kinetic mods1 and found also to be radiatively dominated at low CO concentrations. The importance of radiative trapping and energy transport in evaluating the lifetimes is demonstrated.
