Ir functional group ranges
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. WebFunctional groups are structural units within organic compounds defined by specific atom and bond arrangements. Infrared is a powerful identification tool for functional groups because of the similar absorption frequencies for those groups in different molecules.
