Rate constants are reported for the vibrational deactivation of the asymmetric stretching mode of NsO in the gas phase over the temperature range 300-150 K. Experimental pressures varied between 10 and 600 Torr. The collision partners studied are NsO itself, 02, N2 and CH+ The measurements were made

## Energy transfer between vibrationally excited CO and COz has been used to excite the bendini mode of COa. The rate of deactivation of this mode by CO\* and by Ar has been measured down to 150 K. The followรฏng processes were considered CO@= 1) + co,(ooo) Ke 5 CO(u=O) + CO,(OOl), AE = t206 crneL
Rate constants for the vibrational deactivation of 12C1b by Hz, Dz and 'He have been determined by laser-induced fluorescence in the gas phase at low temperatures. The rate constants for 12C160( u= 1 )-H2 and '\*C?O( u= 1 )-D2 have been measured down to 35 K and those for '\*C%(o= 1 )-'He have been
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.
