✦ Synopsis

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 the isolated binary collision theory.

Rate constants for energy transfer in gases at

temperatures below 300 K are needed for modelling conditions in the upper atmosphere and in lasers operating at low temperatures. They are of crucial importance Volume 76. number 2 CHEhlICAL

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.
