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.

โฆ Synopsis
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.
