The characteristic decay time constant of defocusing thermal lenses was determined in pure benzene, water, chloroform and nitrobenzene, with the use of non-polarized and linearly polarized single heating pulses of a Nd: YAG laser. From the characteristic time constants, the thermal diffusivities wer
