Assigning the 1H-NMR Signals of Aromatic Ring 1H-atoms
www2.chem.wisc.eduAssigning the 1H-NMR Signals of Aromatic Ring 1H-atoms Assigning 1H-NMR signals of 1H-atoms on an aromatic ring based upon their chemical shift and coupling can be accomplished in a number of different ways which will be detailed below. These methods which range from very simple to somewhat sophisticated are complimentary to one
