WebApr 1, 2002 · This is the most important range in the entire IR spectrum for organic chemists. If there is a very strong peak between 1640 and 1850 cm-1, there is most likely a carbonyl function in the molecule. Analysis of the exact peak position will reveal further what type of carbonyl function is present. WebThe carbonyl stretching absorption is one of the strongest IR absorptions, and is very useful in structure determination as one can determine both the number of carbonyl …

WebThe carbonyl stretch C=O of a carboxylic acid appears as an intense band from 1760-1690 cm -1. The exact position of this broad band depends on whether the carboxylic acid is saturated or unsaturated, dimerized, or has internal hydrogen bonding. O–H stretch from 3300-2500 cm -1 C=O stretch from 1760-1690 cm -1 C–O stretch from 1320-1210 cm -1 WebSep 1, 2024 · The carbonyl or C=O group is the perfect functional group for detection by infrared (IR) spectroscopy because its stretching vibration peak is intense and is located in a unique wavenumber range.
