In the course of the last twenty years, light scattering techniques have been used with increasing effort and attention for the measurement of the thermophysical properties of pure fluids and fluid mixtures. These methods work in or close to the thermodynamic equilibrium and can be utilized for the determination of thermal diffusivity, the mutual diffusion coefficient, dynamic viscosity, sound attentuation, surface tension, sound velocity and some derivable thermophysical properties. Some of the relevant developments in this field are reviewed, with emphasis on photon-correlation spectroscopy.
