The vibrational relaxation times of HF(v = 3) and HF(v = 1) in the presence of F atoms have been measured in a slow-flow fluorescence cell at room temperature. The HF is pumped to vibrational levels v = 1, 2, and 3 by a pulsed HF laser. It was found that F atoms deactivate HF(v = 3) faster than they do HF(v = 1) by a factor of 20.8 +- 2.0. This dependence of the deactivation rate coefficient on v agrees with that determined for the exothermic V--V or V-R,T deactivation of HF(v = 1 to 3) by N/sub 2/, O/sub 2/, D/sub 2/, and HCl.
