本文用红外光谱法和激光拉曼光谱法研究了液晶冠醚４一（烯丙基氧）一４′一（４′一羧基苯并一１５一冠一５）联苯在升温时从结晶态到液晶态再到各向同住的液态相转变过程中红外光谱和拉曼光谱的变化。对该液晶冠醚的红外和拉曼特征频串进行了初步的经验式归属，并以频率位移、相对强度及峰形的变化描述了该化合物的相转变并初步讨论了相转变过程中光谱信息与分子结构的关系。
In this paper, infrared spectroscopy and laser Raman spectroscopy were used to study the effect of liquid crystal crown ether (4’-carboxy-benzo-15-crown-5) The changes of the infrared spectrum and the Raman spectrum during the liquid phase transition from the liquid crystal state to the isotropic liquid phase. The initial empiric assignments of IR and Raman frequency bands of the crown ether were described. Phase transitions, relative intensities and peak shapes were also described. The phase transition of the compound was characterized and the spectral information Relationship with molecular structure.
