偏振拉曼光谱在研究分子空间构象中的应用

Application of Polarized Raman Spectroscopy in the Research on Molecule Conformation

偏振拉曼光谱是拉曼光谱中的一种,所有的激发光源和收集的散射光都有确定的偏振方向,不同方向的偏振光检测到样品的特点不同。因此,偏振拉曼光谱在表征样品时,一定要注意偏振方向的选取,以保证样品检测的准确性。文中主要以四氯化碳(CCl4)分子为主要研究对象,通过对其退偏度的计算,推测CCl4的振动方式。所计算的理论值,与实验值相差不大,证明了实验的准确性,同时也说明了偏振拉曼光谱的方向性。

In the present paper, the carbon tetrachloride （CCh） is the main object of study. According to the calculation of the degree of depolarization, the authors can understand CC14 crystal vibration. With the comparison between the calculated theoreti- cal value and the experimental value, we are sure that our work is accurate.
