摘　　要：二维INADEQUATE谱在NMR研究中具有重要价值,本文以二维INADEQUATE谱为主,结合DEPT,同核及异核位移相关谱,指认了δ-维生素E的碳谱谱峰,并由碳氢相关谱给出了各氢的化学位移,本文对δ-维生素E碳谱某些峰和二维INADEQUATE谱做了讨论,并对文献数据做了讨论,并对文献数据做了修正.2D INADEQUATE sequence is one of the most important 2D NMR techniques in current use. By the use of 2D INADEQUATE spectra and DEPT , hetero and homonuclear shift-correlated 2D spectra, the peaks of 13Cspectrum of δ-VEhave been assigned . The chemical shifts of each proton were evaluated by C - H correlate 2D spectra. Some peaks of 13C spectrum of δ-VE and 2D INADEQUATE spectra were discussed , and the data in literature[4] should be amended.
