We present a simple theory of the far-infrared collision-induced absorption spectrum of nitrogen gs. Assuming a quadrupolarinduction mechanism and neggecting the small anisotropy in the Nz pair potential, UT represent the spectral profde as theconvolution of a free-rotalion spectrum with a translati
## Information theory is used to interpret the line-shape of collision-induced absorption spectra of rarqas miWrres Numerical results and comparison with experiment are given for low-density Xe-Ar gas mistures at 295 K.
Accurate quantum-mechanical vakres of the collision-induced absorption coefficient are reported for a Ne-Ar mixture in the binarycollision approximation. Two of the known expressions for the induced dipole moment are tested and two others are proposed to obtain good nyeement with experiment.
Calculations for the collision-induced absorption in a He-Ne mixture in the far infmred (200-600 cm?) are presented. The present calculation includes an exact treatment of the collision dynamics and of the radiation field to the first order. The information used is the interatomic potential and dipo
