✦ Synopsis

The absorption and emission spectra of Mg, Ca, Sr and Ba atoms in superfluid He are calculated systematically by using an adiabatic line-broadening theory modified by inclusion of the bubble-oscillation effect. The present study, which incorporates a more accurate description of molecular electronic states for a diatomic system than that used in an earlier model calculation, results in satisfactory agreement with experimental spectra.

Liquid carbon tetrachloride displays a far-infrared absorption spectrum which is primarily the result of collisional processes involving octapolar and bexadecapolar induction of dipole moments. These moments are modulated by both the rotational and translational motions of the CC4 molecules. The rot
