| 中文摘要: |
| 傅里叶变换红外光谱仪（FTIR）可以获取物质的远红外光谱，并根据其指纹特征光谱对未知样品进行鉴定。在真空条件下运用FTIR测试了可卡因、盐酸氯胺酮、大麻酚、海洛因以及吗啡等五种毒品标准品在远红外波段（30～350 cm-1）的吸收光谱并对部分吸收峰进行了分析。实验结果表明，这五种毒品标准品在远红外波段内均有明显的特征吸收峰。研究结果可为建立毒品的远红外光谱数据库和实现毒品快速鉴别提供参考。 |
| 英文摘要: |
| Fourier transform infrared spectrometer (FTIR) can obtain the far-infrared spectrum of the material and identify the unknown samples according to its fingerprint characteristic spectrum. In this experiment, FTIR was used to test the absorption spectra of five standard drugs, such as cocaine, ketamine hydrochloride, cannabinol, heroin and morphine, in the far-infrared band (30−350 cm-1) under vacuum conditions, and some absorption peaks were described and analyzed. The results show that the five standard drugs have obvious characteristic absorption peaks in the far infrared band. This study provides a data basis for the establishment of far infrared spectrum database for drug identification. |
