采用激光拉曼光谱技术获得了苯的振动拉曼光谱,结合群论分析、退偏度测量和相关文献对其中8条拉曼谱线进行了分析.1550~1650cm。区间内的两条谱线是由于费米共振而形成的.
The vibrational Raman spectra of benzene are obtained by using the laser Raman spectroscopy technology. Combined with the group theory, the depolarization measurement and the relevant literatures, we analyzed 8 characteristic spectrum lines of benzene. Two Raman spectra in the range of 1550-1650cm^-1 are produced by the Fermi resonance.
