In search of high J states in the HF(v, J) system
Abstract
Populations in high rotational states of HF far from rotational-translational equilibrium have been observed in reactive fast flows in a large diameter flow tube. The high rotational states are assumed to be produced from the chemically generated, vibrationally excited HF(v, J) by direct V yields R intramolecular energy transfer collisions with ground-state H2, HF, or Ar species. In a chemical kinetic analysis it is shown that the results are consistent with the multiquantum V yields R energy-transfer mechanism for HF(v, J) + M proposed by R. L. Wilkins for HF(v, J) + HF and D. L. Thompson for HF(v, J) + Ar. Experimental studies are made by monitoring HF R-R spectral emissions between 9 to 22 micrometer with a sensitive bolometer.
