WitrynaNMR Spectroscopy. The amine proton(s) show(s) as a broad peak (but not as broad as a carboxylic acid proton peak) from 0.5–3.0 ppm if the amine is aliphatic; 3–5 ppm if the amine is aromatic. The proton on a carbon adjacent to the amine group is found from 1.5–2 ppm. IR:Examples: 2-Ethylaniline (11) and diisopropylamine (12).
