The equilibration of the lower laser levers in COz, loo0 and 02O0, has been studied via a laser-induced fluorescence technique. We conclude that the coupling between these leveis is rapid, >llOO ms-' To& I and that these levels are also coupted though at a somewhat slower rate of 387 f 75 ms-\* Torr

Rapld, selective colhsion-dependent excitation of NzO following pumping of SF6 with a CO2 laser is reported. The NzO fluorescence nse depends on the pressure of each component and is dominated by the SFe-dependent contribution of 2290 ms-t To& \_ The subsequent fall is governed by V +V processes amo
Rate constants for vibrational energy transfer have been measured in the system N2( v= 1) +CO( u= 0) as a function of energy mismatch by using isotopic derivatives of N2 and of CO. These rate constants have been determined both in the gas phase and in liquid argon solution at 8 5 K. For non-resonant
