Abstract
The self-shifts of the lines in the fundamental of HF from P(7) to R(8) and the line shifts in the first overtone band of DF when perturbed by HF were measured from P(7) to R(6). Pressure-induced shifts in the HF fundamental were studied at room temperature and at pressures of HF varying from 375 to 1135 torr. The shifts agreed with those observed by Herndon, but the estimated error 0.5 × 10−5 cm−1/torr for the present study was about one third of that of Herndon. The partial pressures of DF ranged from 361.2 to 1218 torr. Temperatures of reference and sample cells were 383, 393, 423, and 407 K. The shifts oscillate with a period of one in J and with increasing amplitude in the wings from R(1) to R(6) and P(3) to P(7). The direction of the shifts is the same as that found for the DCl–HCl system and is opposite to that predicted by the simple near-resonant dipole theory. The shifts in the present study are considerably larger than those found from the DCl-HCl study.
