摘    要:采用显微共聚焦拉曼光谱对三种二元水溶液(乙腈/水、二甲基亚砜(DMSO)/水和丙酮/水)进行测量,得到含有氢键作用的水溶液体系拉曼频移和线宽随浓度的变化规律。应用混合模型和相互作用体系的线宽经验公式对实验结果进行了分析。结果表明,含有氢键作用的水溶液体系中,氢键作用越强线宽越大,并且线宽随单位浓度变化率大;同种氢键体系中,线宽不仅受浓度浮动的影响,氢键作用也是一个重要的影响因素,定量分析证明线宽与浓度、氢键作用关系很好地符合Ojha等提出的线宽公式。

关 键 词:氢键  线宽  拉曼光谱  水溶液

Abstract:In the present paper, the frequency shift and line widths of acetonitrile/H2O, DMSO/H2O and acetone/H2O aqueous binary solutions at different concentration were measured by Raman spectroscopy. The experimental results were analyzed by mixture model and empirical formula of line widths. The results show that the stronger the hydrogen bond interaction, the greater the line widths of Raman spectra in the three aqueous binary solutions; the line width of Raman spectra not only is affected by concentration fluctuation, but also is affected by hydrogen bond. In addition, the experimental data points are again nicely fitted using the empirical formula.
Keywords:Hydrogen bond  Line width  Raman spectra  Aqueous solution
