In general, C-O stretching peaks are intense and normally fall between 1300 and 1000 cm-1 (going forward assume all peak positions are in cm-1 units). Because this wavenumber range is in the fingerprint region (2) there are often many peaks present between 1300 and 1000, but again the distinguishing feature of C-O stretches will be their intensity.The vibration at 1507 cm − 1 is assigned to the mixed vibrations of C=O and C-C=O groups, characteristic of the β-diketone group, while the C-O peak of the enol group is identified at 1272 cm ...If a compound is suspected to be an aldehyde, a peak always appears around 2720 cm-1 which often appears as a shoulder-type peak just to the right of the alkyl C–H stretches.
