摘要
随着高分辨光谱技术和原位技术的发展,原位拉曼光谱的研制促进一系列原位微观物理化学行为及机理的研究,对材料的设计和应用有着重要意义.本文从拉曼光谱的原理及拉曼信号的影响因素出发,概述原位拉曼光谱技术用于反应和结晶控制的具体实例,总结原位拉曼光谱在化学反应和溶液结晶中晶体多态性、中间体和产物微观结构、化学键合模式等方面的研究进展,为研究反应及结晶机理提供重要线索,并对原位拉曼光谱技术的发展趋势进行了预测.
With the development of high-resolution spectroscopy and in situ technology,the development of in situ Raman spectra promotes a series of in situ researches about micro-behavior and mechanism of physics and chemistry over time,which has great significance for the design and application of materials.Based on the principles of Raman spectra and the factors affecting the Raman signal,this paper summarizes the specific examples of in situ Raman spectroscopy applied to reaction and crystallization control.The research progress is concluded that in situ Raman spectra detects the variations of crystal polymorphism,microstructure of intermediates and products,and chemical bonding mode in chemical reaction and solution crystallization,which provides important information for the study of reaction and crystallization mechanism.The development trend of in situ Raman spectroscopy is also predicted.
