| Abstract: | After recalling briefly the results of the analysis of a forced Rayleigh experiment in a binary fluid mixture, one shows data obtained in a carbon disulfide-ethanol mixture. Estimating the derivatives of the susceptibility of the mixture from the Lorentz-Lorenz formula, one obtains values for the thermal diffusion ratio for several concentrations. |
