Two 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.
