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 NO(1)+NO(1)→NO(0)+NO(2) was obtained.
