摘　　要：缔合溶液具有与理想溶液显著不同的热力学和谱学性质,对于热力学和谱学的研究,有助于我们理解缔合溶液的特殊行为.谱学技术中核磁共振(NMR)、红外(IR)和拉曼(Raman)光谱是研究分子间相互作用和溶液结构等微观性质的有效方法,谱学已成为分子热力学研究体系"四面体结构"中的第四个顶点.本文对缔合溶液中热力学(汽液平衡和焓)和谱学(NMR,IR和Raman)联系的最新研究进展进行了综述,着重介绍相关的模型,如化学缔合模型、局部组成(LC)、格子流体氢键(LFHB)理论以及统计缔合流体理论(SAFT).The macroscopic properties of associated solution systems reveal particularity in comparison with the ideal solution,such as thermodynamic properties and spectroscopic properties.The study on thermodynamic properties and spectroscopic properties can help us to understand special behavior of associated solutions.Spectroscopic technology including NMR,IR and Raman is an effective method to investigate the microscopic properties such as intermolecular interactions and solution structure which has become the fourth vertex on the molecular thermodynamics tetrahedron.As a result,spectroscopy can be regarded as a tool to study thermodynamics of solution system,and there may be some relationships between the spectroscopic properties and thermodynamic properties.In this paper,the recent progress in the studies of the spectroscopic properties of associated solution,as well as the relationships between the spectroscopic properties （NMR,IR and Raman） and thermodynamic properties （vapor-liquid equilibira and enthalpy） are introduced and reviewed.The various models various models which are present to describe the spectroscopic properties and relate to the thermodynamic properties,such as chemical association model,local composition （LC） model,the lattice fluid hydrogen bonding （LFHB） theory and the statistical associating fluid theory （SAFT） are also discussed.
