Far infrared interaction induced absorption spectra of CS2−C6H6 liquid mixtures. A low concentration study Original Research Article

We report the statis and dynamic interaction induced properties of CS2−C6H6 liquid mixtures, particularly at low benzene concentrations, as studied by far infrared absorption spectroscopy. The experimental effective dipole moments are compared with the calculated one, obtained from a simplified approach based on a quadrupole induced dipole mechanism. The dynamic functions are quantified with the Gaussian cage model. The results reinforce the evidence of stronger intermolecular interactions and the formation of ‘transient clusters’ in the mixtures, as found in our previous study.
