title: [Studies of narcotics by micro Raman spectroscopy].
abstract: 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.
