An IR spectrum is defined by the presence of intense signals at specific wavelengths, such as 2110 cm−1, which are characteristic of functional groups like C=C=O. AI generated definition based on: Coordination Chemistry Reviews, 2003
Spectroscopic control is performed with the aid of an auxiliary adsorbent, which is transparent in the infrared region of the spectrum and has hydroxyl groups on its surface. This method can be employed to determine the content of functional groups, capable of deuterium exchange, on the surface ...
(Functionalgroupsandcharacteristicfrequency)特征频率是识别官能团的重要依据，它并非一成不变，而是处于一个区间内。通常，将一张红外光谱图分为两部分。1.4000～1500（或3800～1350）cm－1，是高波数区。特征吸收出现较多的区域，主要由伸缩振动引起，受其它因素影响小，称为基频区。2.1500以下（或1350～600）cm－...

INFRARED (IR) SPECTROSCOPY (SPECTROPHOTOMETRY) The interaction of Electromagnetic (EM) radiation with matter is one of the most useful phenomena available to chemists for the identification and quantization of unknown substances. You have already studied spectrophotometry involving the visible spectrum (colo...
