Interpretation of dipole correlation functions in some liquid systems
Abstract
The dipole correlation functions determined from far infra-red absorption measurements of a variety of liquids are compared with correlation functions calculated with different models for the motion of the molecules. These models vary from simple rotational diffusion models to models derived from solid state theory. Experimental results are presented of far infra-red measurements of HCl dissolved in liquid argon and of solutions of CH3CN in some organic solvents. For these liquid systems good agreement can be obtained between experiment and model calculations. It is pointed out that the description of these systems in terms of a model has a strong phenomenological character.
