Abstract
The thermal diffusivity of three pure liquids-acetone, benzene and toluene- has been measured by Rayleigh scattering of laser light and a digital correlation technique. The obtained values are accurate to 4 per cent and are in good agreement with those derived from conventional measurements of density, specific heat and thermal conductivity. A critical analysis of the technique is given.Keywords
