Abstract
We describe the application of the photoacoustic technique to the thermal characterization of liquids. An experimental method which allows the experimental determination of the thermal effusivity in transparent as well as in light absorbing samples is proposed. The method is tested by measurements in water, ethanol, diffusion-pump oil, glycerol and petroleum. Our results agree quite well with the literature reported values for these samples.
