卷烟的喇曼光谱分析

Analysis of Raman Spectral Characteristics of Cigarettes

喇曼光谱是研究物质内部结构的一种有效手段,不同的物质或各组成成分配置比例不同的物质,它们将具有不同的喇曼光谱形状。文章介绍了振动喇曼散射的基本原理,使用激光喇曼光谱仪测量了几种常见卷烟的喇曼光谱图。通过对这些光谱图进行比较分析,得出由卷烟的喇曼光谱图识别其品质优劣的参照方法。

Raman spectrum is an effective method to study the interior structure of substance.The different material or the same kind of material with different structure has its own Raman spectrum.The basic principle of resonance Raman spectrum and experiment method are discussed.Ales,the Ramón spectra of some kinds of cigarette have been obtained with the excitation laser at 532nm.Compared to these spectra,the referent emoted to distinguish the quality of different kind of cigarette was obtained.
