| Abstract: | The 1H NMR spectra of 19 phenol compounds were analysed and studied here . The result showed that when intramolecular hydrogen bond is formed at the phenolic hydroxyl group the resonace of the para-aromatic hydrogen shifts to higher magnetic field. This shift is greater than that of the ortho-aromatic hydrogen. The diffence is about 0. 1ppm-0.3 ppm. |
