“…Indeed, the latter has been found to be the case for the molecules HCl, HBr, and HI [ I ] . I n a recent paper [4] we reported the following expression for the autocatalytic vibrational relaxation of HF: 64 f 4 ( 7 P ) & H F = 10 9.2 f0.1 exp (-7) atm-'set-1 where (~P ) A -B is the time for relaxation of A by B when the latter is at atmospheric pressure. In the present work we have extended this study to the relaxation of the deuterated molecule in an effort to more clearly elucidate the energy transfer mechanism for these molecules.…”

The vibrational excitation of H F and DF and the energy transfer efficiencies for various collision partners were investigated over the temperature and pressure ranges of 1400°K to 4100°K and 0.1 to 0.3 atm, respectively. The extent of excitation was determined as a function of time by continuously monitoring the infrared emission intensity at the center of the 1-0 vibration-rotation band of the molecule. Collisional efficiencies of HF, NB, 02, F, C1, and DF in relaxing H F and of DF, HF, and Nf in relaxing DF are reported. A comparison with relaxation data for pure H F taken at lower temperature suggests that long-range attractive forces are mechanistically of major importance in the relaxation process. The relatively high efficiency of atomic chlorine in relaxing HF, i.e., (TP)HF-HF/ ( T P ) H F -c~ 2 5 at 3000°K is discussed in terms of our previous result for atomic fluorine, i.e., (TP)HF-HF/(TP)HF-F = 18.

“…It is possible that overinitiation dissociates the reactants, producing radicals which are known to rapidly deactivate HF + . 92 An interesting characteristic of these systems is that in some cases the laser pulses are unusually long at low initiation energies, which might be an indication of chaining reactions.…”
