摘要：
H-1 NMR measurements and A initio calculations were used to study the interactions between hindered/nonhindered phenols and carboxylic acid esters. The dihedral angle (phi) between the OH group and a plane of the aromatic ring is close to 01 in the hydrogen-bonded nonhindered phenols, whereas for 2,6-di-tert-butyl-4-methyl phenol the OH group is completely twisted out of the aromatic plane (phi approximate to 90degrees).
