N2 - The analytical solution for the one-dimensional heat diffusion problem for a two layer system, in the Beer-Lambert model for light absorption, is shown to be useful for the implementation of a novel photoacoustic methodology, in the rear configuration, for the measurement of thermal and optical properties of dye solutions. The photoacoustic signal as a function of the sample's thickness is used for this goal. This methodology was tested by measuring the optical absorption coefficient (at 650 nm) and the thermal diffusivity for a solution of methylene blue in distilled water at various concentrations.
