一、前言红外光谱是分析有机物结构的重要手段。常规的有透射法,反射法进行测量,对某些特殊样品(如难溶、难熔、难粉碎等的试样)的测试存在困难。为克服其不足,20世纪60年代初出现了衰减全反射(ATR)红外附件,但由于受当时色散型红外光谱仪性能的限制,ATR技术的应用研究领域比较局限。80年代初将ATR技术开始应用到傅里叶变换红外光谱仪上,产生了傅里叶变换衰减全反射红外光谱仪(ATR-FTIR)。ATR的应用极大地简化了一些特殊样品的测试,使微区成分的分
I. Introduction Infrared spectroscopy is an important means of analyzing the structure of organic compounds. Conventional transmission method, the reflection method of measurement, for some special samples (such as insoluble, refractory, difficult to smash the test) difficult to test. In order to overcome its shortcomings, attenuated total reflection (ATR) infrared attachment appeared in the early 1960s, but due to the limited performance of the dispersive infrared spectrometer at the time, the applied research field of ATR technology is limited. In the early 1980s, the ATR technology was applied to the Fourier transform infrared spectrometer, resulting in a Fourier transform attenuated total reflection infrared spectrometer (ATR-FTIR). The application of ATR greatly simplifies the testing of some special samples, making the fraction of micro-domains
