摘要：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。

关键词：偏振拉曼;退偏度;分子振动;四氯化碳(CCl₄)

Abstract：In the present paper, the carbon tetrachloride (CCl₄) is the main object of study. According to the calculation of the degree of depolarization, the authors can understand CCl₄ crystal vibration. With the comparison between the calculated theoretical value and the experimental value, we are sure that our work is accurate.

Key words：Polarized Raman;Degree of depolarization;Molecular vibrations;CCl₄
