• The nuclear magnetic resonance in dimethylphenols were observed. The dependences of the chemical shifts for the methyl, hydroxyl and ring protons on solvent and concentration were measured and several clear differences were observed among the spectra of the isomers. The phenols with one or two ortho methyl groups showed peculiar behaviors which may be ascribed to the interaction between the hydroxyl group and the ortho proton or ortho methyl protons. The evidience of the steric hindrance of the ortho methyl group to form an intermolecular hydrogen bond is also shown in the present measurements.
