Research on Raman Redshift Spectra of Organic Compounds CCL₄ and C₂H₆O

本文基于785 nm拉曼激光作为激发光源设计检测系统研究液体样品四氯化碳CCL₄分子和乙醇溶液的拉曼光谱，并通过对拉曼激光系统的优化以及拉曼光谱的分析，不仅精确测定了CCL₄分子和乙醇溶液拉曼位移的数值，还提高了对拉曼散射效应的认识。结合所测的乙醇与CCL₄分子的光谱结果并进行数据优化，讨论了其拉曼活性、相对强度、分子振动模式和拉曼特征峰的关系等光谱特性。本文的研究结果不仅丰富了上述两类被测材料的微观信息，还系统认识了它们的光谱识别方法。
In this paper, based on the 785 nm Raman laser as the excitation light source, a detection system was designed to study the Raman spectra of the liquid samples of carbon tetrachloride CCL₄ molecules and ethanol solutions. Numerical values of Raman shifts for molecules and ethanol solutions also improve understanding of Raman scattering effects. Combined with the measured spectral results of ethanol and CCL₄ molecules and optimizing the data, the spectral characteristics such as Raman activity, relative intensities, molecular vibration modes and the relationship between Raman characteristic peaks were discussed. The results of this paper not only enrich the microscopic information of the above two types of tested materials, but also systematically recognize their spectral identification methods.
