摘要
Abstract
Raman spectra of toluene were obtained by using laser Raman spectroscopy.Combined with the group theory and the depolarization ratio analysis , the vibration modes of 16 spectral lines of toluene were assigned. These results provide the basis for the recognition of toluene in organic mixture.Toluene/CCl4 mixtures with dif-ferent concentrations were analyzed,choosing 1 008.8 cm-1 vibrational Raman spectral line of toluene as detec-tion spectrum.The results show that, the linear relationship between the Raman spectral intensity ratio of tolu-ene/CCl4 and the concentration of toluene in 200.1~2.61 g/L concentration range was obtained.The linear cor-relation coefficient is 0.997.It is proved that this spectral measurement method is a potential tool for quantitative analysis of toluene.关键词
