| 摘 要： | 首次发现二甲基甲酰胺(DMF)溶液在添加适量的四(对硝基苯)卟啉(PNNNN)后,其865cm~(-1)处的Raman振动模所对应的CARS(相干反斯托克斯喇曼散射)光谱信号有明显的增强效应.从实验和理论两方面探讨了添加剂浓度变化对这种光谱信号增强效应的影响,并在四波混频理论的基础上,对上述增强效应的产生机理做了较细致的定性分析。

| Abstract: | The single-shot coherent anti-Stokes Raman scattering spectra of liquid N, N-Dimethylformamide (DMF) when mixed with nitrotetraphenylporphin (PNNNN) in different concentrations have been obtained experimentally. The results show that the additive PNNNN has enhanced the intensity of the CARS resonance line 865cm-1 of DMF relative to other CARS lines of DMF. This phenomenon is interpreted as the mutual effect between different molecules by an analysis of third -order susceptibility. |
