摘要
激光偏振喇曼光谱在确定分子振动模的对称性和红外光谱结构分析方面具有重要作用,本文报道了利用532nm激光从实验上测定了丙酮、甲醇、乙二醇和甲酰胺分子的激光偏振喇曼光谱,确定了各喇曼谱线对应的喇曼频移。测定了丙酮、甲醇、乙二醇和甲酰胺分子各喇曼频移对应的退偏比,并对各条谱线所属正则振动模的对称性进行了初步分析。
The polarized laser Raman spectrum plays an important role in analyzing the symmetry of the normal vibration mode and the structure of 1R spectrum of molecule. In this paper the polarized laser Raman spectra of acetone , methanol,Ethylene glycol, formamide are measured and the Raman shift of each spectral line is obtained with the laser wavelength at 532nm. The depolarization ratio of every measured Raman shift and the symmetry of the corresponding mode are determined.
