导数光谱法(Derivative Spectrometry)是近年来发展较为迅速的一种技术。早在50年代中期,Giese等就利用微分方法解决了光谱的重叠问题。随着现代电子技术的迅速发展,特别是分析仪器上使用了计算机,导数光谱的应用更为广泛。尤其在可见——紫外分光光度法中的应用更为突出。目前导数光谱法在红外 Derivative Spectrometry is a technique developed rapidly in recent years. As early as the mid-1950s, Giese et al. Used differential methods to solve the problem of overlapping spectra. With the rapid development of modern electronic technology, especially the computer using analytical instruments, the application of derivative spectroscopy is more extensive. Especially in the visible - UV spectrophotometry more prominent. The current derivative spectroscopy in the infrared
