Abstract
Comparison of the experimental1 and theoretical results2 for the collision induced lineshift values in rotational spectra of HF in Ar gas has shown that there is a great systematic difference between these data at higher J values. The theoretical shifts are negative and tend to zero, whereas the experimental ones become positive and increase with line number. Since the lineshift data ofRef. 1 were obtained at rather high density ofAr, we have studied the HF-Ar spectra at lower pressures from 1 to 30 bars to exclude the possible non-linear dependence on gas density.
