摘要：

The lineshapes of collision-induced absorption (CIA) at room temperature are computed quantum mechanically for gaseous binary mixtures of helium with xenon using theoretical induced dipole moment and interatomic potentials. Empirical and literature models of the induced dipole moments which reproduce the experimental spectra and the first few spectral moments are given. Good agreement between the computed and experimental lineshapes of absorption is obtained when the potential parameters which are fitted well to the vibrational energy levels, thermophysical and transport properties are used.
