WebbIR Spectroscopy Tutorial: Ketones The carbonyl stretching vibration band C=O of saturated aliphatic ketones appears at 1715 cm -1. Conjugation of the carbonyl group with carbon-carbon double bonds or phenyl groups, as in alpha, beta-unsaturated aldehydes and benzaldehyde, shifts this band to lower wavenumbers, 1685-1666 cm -1. See also: WebbThe distinguishing feature on infrared spectra of ketones and aldehydes is the strong carbonyl absorption that occurs at about 1700 cm-1. The difference between the …
