Spectral Lineshape Parameters Revisited for HF in a Bath of Argon.
Previous measurements of asymmetries of the profiles of argon-broadened HF lines at moderate perturber densities (pressures higher than 10 atm) have been confirmed and extended by high-resolution Fourier transform spectroscopy. In some cases, the asymmetries observed here are of opposite sign when compared to the results obtained at much lower densities (pressures lower than 1 atm). By comparing all the available experiments, the competition between the various mechanisms leading to asymmetries has been analyzed as function of the perturber pressure and the vibrational transitions considered.
