摘要: 通过对19个酚类化合物1H NMR谱的研究和分析发现,酚羟基形成分子内氢键后,使对位芳氢化学位移值向高场变化的幅度大于邻位,其差值约为0.1ppm-0.3ppm.

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.
