  • 测量了苯在八种溶液中不同浓度下联合散射谱带992厘米-1的积分强度及溶液折射率。研究了谱带强度、浓度、折射率与苯在这些溶液中吸收频率之间的相互关系。结果表明,谱带强度随浓度的偏离系与溶液折射率与苯折射率之差成正比。在不同溶液中的谱带强度与其折射率成直线关系,即强度与溶液的性质无关,只与折射率有关。谱带强度与苯在这些溶液中的吸收频率共振因子成正比关系,从介质对电子吸收谱带的扰动观点以共振联合散射效应讨论了实验结果。
    The correlations between the Raman band intensities, concentrations, refractive indices and the absorption frequency of benzene were studied by measuring the integrated intensities of the Raman band 992 cm-1 of benzene in 8 solutions of different concentrations and the refractive indices of the solutions. It is shown that the intensity deviation is proportional to the difference between the refractive index of the solution and that of pure benzene. The band intensities of different solutions depend linearly on their refractive indices, that is, the intensity does not depend on the nature of the solvent, but on its refractive index. The relationship between the band intensities and the resonance frequency factors of benzene in the solutions is also linear. The experimental results are discussed from the point of view of perturbation of the medium on the electronic absorption band.
