摘要
用１３Ｃ－ＮＭＲ谱和二维异核化学位移相关谱（ＨＥＴＣＯＲ）归属了酞侧基聚芳醚砜（ＰＥＳ－Ｃ）的１Ｈ－ＮＭＲ谱峰，并经二维同核化学位移相关谱（ＣＯＳＹ）验证．对原１３Ｃ－ＮＭＲ谱峰归属作了部分修正．二维同核及异核相关谱为ＰＥＳ－Ｃ的碳、氢核磁谱峰归属提供了重要信息．
wo dimensional heteronuclear correlated spectroscopy(HETCOR)together with the 13C-NMR spectrum are used to make line assignments of phenolphthalein polyethersulfone(PES-C). These assignments are confirmed by two dimensional homonuclear correlated spectroscopy (COSY). A little modification is made on the original 13C line assignments. Homonuclear and heteronuclear correlated spectroscopy present important information on assigning the spectra lines of PES-C. From the NMR spectra of PES-C the isotacticity of its chain structure is obvious.
