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. WebJul 1, 2024 · The IR Spectroscopy of Esters Note that ester groups contain one C=O bond and two C-O bonds. We have already studied the IR spectroscopy of both these functional groups, so we can take a stab at predicting what their spectra might look like.
