摘要
使用拉曼光谱研究二元水溶液(H2O-DMSO)中的氢键作用及其对二元体系中水溶液结构的影响.实验结果表明:DMSO与水之间的氢键作用使DMSO的S=O键发生红移,水分子的O—H键蓝移,对二元体系水溶液体系的微观结构产生极大影响.该项研究有利于丰富二元、多元水溶液氢键结构体系,为相关水溶液体系的物理化学性质的解析提供有价值的实验数据.
Raman spectroscopy was used to study the hydrogen bonding in aqueous solution(H 2O-DMSO)and the influence of the hydrogen bonding on the structure of the binary aqueous solution.The experimental result showed that the hydrogen bonding caused the S=O bond of DMSO to shift red,and the O—H bond of the water to shift blue in the binary aqueous solution,which affected the micro structure of the binary aqueous solution system.An experimental basis was provided for enriching the hydrogen bonding theory of multivariate aqueous solution systems.
