Web[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules. WebIR SPECTRUM OF AMIDES The amide functional group combines the features of amines and ketones because it has both the N-H bond and the C=O bond. Therefore amides show a …
