FOREIGN GAS BROADENING AND SHIFTING IN HF.

Author Institution: Department of Physics, Pennsylvania State UniversityThe broadening and shifting of lines in the 2-0 band of HF have been investigated for argon, krypton and xenon at room temperature and $150^{\circ}$ C. The shifts measured are in accord with the results of Jaffe, Rosenberg and Hirschfeld in that the shifts with xenon are smaller than with krypton as the foreign gas. This is contrary to the results found in HCl. Line broadening studies show that with argon the results are as would be expected from comparison with HCl. However, with xenon the broadening coefficient increases with increasing J. With krypton the broadening coefficient increases for high J lines. Work on the 1-0 band is in progress
