✦ Synopsis

The laser induced fluorescence method has been used to measure the rate of deactivation of HF(u = 1) by F, 0, and H atoms at 300°K. The rate for F-atoms was found to be kF_HF = (0.9 f 0.2) X lo4 set-' torr-', for Oatoms Lo_m = (1.0 f 0.2) X lo5 set-' torr-', and for Hatoms, an upper limit to the rate was found to be k&m < 0.5 X lo3 set-' torr-' . The results are explained qualitatively in terms of a vibronic to translational energy transfer mechanism.
