摘要
利用显微拉曼技术对八种常见毒品做了测试和分析， 得到拉曼散射谱。对毒品拉曼谱和分子结构的分析表明： 取代支链上甲基的数目和位置对拉曼谱线均有明显的影响。在激发光５１４．５ ｎｍ 下， 几种常见的毒品都具有不同程度的荧光， 采取合适的测试条件， 对减小拉曼谱的荧光有明显的作用。此外实验中发现那可汀和蒂巴因对强光照射比较敏感，因此控制样品表面的激光功率约１ ｍ Ｗ 左右。最后分析比较毒品的拉曼谱， 给出它们的拉曼谱线，
For the first time,the Raman spectra of eight kinds of narcotics were obtained and investigated by micro Raman.The results indicated that the Raman spectra were affected by the numbers and position of methyl in substituent groups.Under incidence light 514 5 nm and appropriate measurement condition,high quality Raman spectra of drugs with low fluorescence background were obtained.In addition,we discovered that narcotine and thedaine were very sensitive to strong light radiation.Finally,by comparing Raman spectra carefully for all drugs we measured the specific Raman peaks were given for the purpose of distinguishing different kinds of drugs.
