✦ Synopsis

The fundamental infrared spectra (2700-3100 cm-') of dilure solutions of HCI in liquid SF, at temperatures between 2 18 and 316 K have been calculated by applying a spectral theory based on the decomposition of the rotational motion of the diatomic molecule into two limiting cases: quasi-free rotation and rotational diffusion. From comparison between theoretical and experimental spectra it is possible to deduce quantitative values for a reduced set of statistical parameters involved in the theory and to analyze their behaviour as a function of the solvent temperature. The connection between the rotational structure appearing in these spectra and the parameters is discussed.

The far-infrared of DCI, HCl and HF in liquid SF, (T= 273 K) are studied by applying a previously reported non-Markovian line-by-line spectral theory in which memory and mixing effects arc explicitly considered. We analyze the importance of both effects in terms of the rotational constant of the dia
