WebCarbons in an aromatic ring absorb in the range of 120-150 ppm in a 13 C NMR spectrum. This is virtually the same range as nonaromatic alkenes (110-150 ppm) so peaks in this region are not definitive proof of a molecule's aromaticity. Due to the decoupling in 13 C NMR, the number of absorptions due to aromatic carbons can easily be observed. hibah maisWebThe 1 H NMR chemical shifts for phenols are not particularly distinctive.
