Surface tension and Raman spectra containing hydrogen bonding in acetonitrile aqueous solutions with different mole ratios were obtained. Varied surface tension and hydrogen bonding in the mixed solution were discussed. For this purpose, the OH stretching bands were fitted into three Gaussian components to which different hydrogen-bonded water samples were assigned. Furthermore, the microstructures of binary solution were analyzed. The results indicated that the surface tension decreases dramatically with the enhancement of hydrogen bonds in the mixture. A spectroscopic method for studying the macroscopic properties of aqueous solutions was employed. The direct experiment results provided the relationship between surface tension and microstructure in aqueous solutions.

用拉曼光谱研究基于氢键的微结构对表面张力的影响。

获得了不同摩尔比的乙腈水溶液中含有氢键的表面张力和拉曼光谱。讨论了混合溶液中各种表面张力和氢键。为此,将OH拉伸带装配到三个高斯分量中,并为其分配了不同的氢键水样。此外,分析了二元溶液的微观结构。结果表明,随着混合物中氢键的增加,表面张力急剧下降。采用光谱法研究水溶液的宏观性质。直接的实验结果提供了水溶液中表面张力与微观结构之间的关系。
