Vibrational energy transfer in NO

Abstract

Laser‐excited vibrational fluorescence measurements have been used to obtain rate constants at room temperature for vibrational relaxation of the V = 1 state of NO in collisions with He, Ar, H₂, CO, NO, N₂, and CO₂. Pulses from a CO₂ laser, frequency doubled in a tellurium crystal, provided the excitation source. The rate for the V‐V exchange $\mathrm{NO}\text{(1)+}\mathrm{NO}\text{(1)→}\mathrm{NO}\text{(0)+}\mathrm{NO}\text{(2)}$ was obtained.
