Assigning the 1H-NMR Signals of Aromatic Ring 1H-atoms

the signals in the aromatic region. 3) Model compound An often over-looked and under-utilized method of assigning the signals in the 1H-NMR region is by comparison to known molecules. Let us assume that the 1H-NMR spectrum of o-isopropylaniline is not available in any database. It is very similar to at least three common compounds (benzene,
