We have developed a pulsed photothermal radiometry technique for determining the thermal diffusivity parallel to the surface of a polymer film that involves flashing a line-shaped laser beam on the surface of the sample at right angle to its length, and monitoring the temperature change with time at

The thermal diffusivity of pig abdomen stratum corneum has been determined using photothermal beam deflection measurements and time-resolved mode mismatched thermal lens spectrometry . The most precise determination (2 .9 Β± 0.5 x 10 -4 cm2 s -1 ) was obtained using the thermal lens technique. The pr
## Abstract The measurement of diffusion coefficients in multicomponent liquid mixtures is still an open question. A new technique aimed at overcoming this deficiency is presented. It is based on Raman spectroscopy, which has been extended to obtain liquid concentration data of all components in a
