傅里叶变换红外光谱(FTIR)的出现,使红外光谱技术突破分光型红外光谱术的局限性得以复兴。红外光谱法能以崭新的面貌出现主要决定于其独特的优点:红外法普适性强,气、固、液的样品都可测试而不破坏原样;它不仅是结构研究的强有力工具,也是分析鉴定的有效方法,再配合显微红外等附件技术,使红外光谱几乎成为一种全能的技术,其不仅在化学各学科中应用很广,在医药、环境等许多相关学科也有着重要的应用。每个化合物都有自己特有的红外吸收频率和强度,在药物分析中利用红外光谱具有“指纹图”的特
The emergence of Fourier transform infrared spectroscopy (FTIR), the infrared spectroscopy to break through the limitations of spectroscopic infrared spectroscopy to be revived. Infrared spectroscopy can be a new look mainly due to its unique advantages: Infrared law universal, gas, solid, liquid samples can be tested without breaking the original; it is not only a powerful tool for structural studies, but also Analysis and identification of effective methods, coupled with the microscope and other infrared attachment technology, the infrared spectrum has almost become an all-around technology, which not only in a wide range of chemical disciplines, in medicine, the environment and many other related disciplines also has an important application . Each compound has its own unique infrared absorption frequency and intensity, the use of infrared spectroscopy in the drug analysis has a “fingerprint” special
