In the present study, pump-probe thermal lens spectroscopy was used to probe the thermal behavior and molecular interactions in the binary liquid mixtures of acetone, and 1-alkanol. Values of thermal conductivity, thermal diffusivity and thermo-optical parameters were measured for the above liquids. Experimental measurement for the pure state and binary fluids are in good agreement with the literature data. Changes in the measured parameters indicate that these result from a combined effect of physical and molecular properties of binary liquids. Furthermore, the Soret coefficient S_T of alcohols in the binary mixtures was calculated by two methods. Findings demonstrate that increasing the chain length of alcohol reduces its tendency to interact with acetone.

在本研究中，泵-探针热透镜光谱用于探测丙酮和 1-烷醇的二元液体混合物中的热行为和分子相互作用。测量上述液体的热导率、热扩散率和热光参数值。纯态和二元流体的实验测量与文献数据非常吻合。测量参数的变化表明，这些变化是由二元液体的物理和分子特性的综合影响造成的。此外，索瑞系数小号_Ť在二元混合物的醇的通过两种方法进行计算。研究结果表明，增加醇的链长会降低其与丙酮相互作用的趋势。
