✦ Synopsis
qualitative explanation is given for the shape of the bands of dissolved polar molecules (in liquid or compressed polar solvents) observed in infrared spectroscopy; the influence of hindering potentials for the free rotation of the dissolved molecule is taken into account to explain the general appearance of a strong central maximum in these bands.' Assuming the simultaneous existence of molecules influenced by various intensities of these hindering potentials, one can interpret the subsidiary maxima sometimes observed in the vibrational bands in dense solvents. The cage model has been used to describe statistically the spatial distribution of the perturbing molecules.
