液态水和水溶液的结构是当今最基础且最具挑战性的科学问题之一。氢键作用作为液态水分子缔合的根本原因，也直接影响水溶液的物理化学性质。本项目拟采用偏振拉曼光谱和液芯光纤拉曼光谱作为主要实验手段，结合量子化学计算的方法，研究一系列具有典型氢键作用的水溶液体系，从分子层次上揭示氢键对水溶液体系的作用规律。同时，本项目拟开展具有典型氢键作用的水溶液体系的宏观物理化学性质的测量，结合水溶液微观结构建立氢键作用-水溶液微观结构-宏观性质的关联模型，为丰富水科学研究提供有价值的实验依据。

The structures of liquid water and aqueous solution are one of the most basic and challenging scientific problems.As the fundamental cause of the association of liquid water molecules, hydrogen bonding has a direct influence on the physical and chemical properties of aqueous solutions.In this project, we will employ the polarization Raman spectroscopy and liquid-core optical fiber Raman spectra technology as the major means of experiment,with the combination of quantum chemistry calculation method to study a series of typical system of aqueous solution with hydrogen bonding, the effect of hydrogen bond on aqueous solution system is revealed at the molecular level. Meanwhile, we will carry out the measurement of the physical and chemical properties of aqueous solution system with hydrogen bond, combined with the aqueous solution microstructure to establish the correlation model of hydrogen bonding, aqueous solution microstructure and macroscopic properties，and provide valuable experimental basis for enriching water science research.
