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. itunes without downloadingWebAug 6, 2014 · Phenol, 4- (1,3,5-trimethylhexyl) Other names: Phenol, nonyl- Information on this page: IR Spectrum References Notes Other data available: Gas Chromatography Options: Switch to calorie-based units IR Spectrum Go To: Top, References, Notes Data compilation copyright by the U.S. Secretary of Commerce on behalf of the U.S.A.
