Abstract: In this paper the 13C NMRresearch of 3-bromo-carbazole, 3,6-dibro-mo-carbazole, 9-(2',3'-epoxypropyl) carbazole, 9-(2',3'-epoxypropyl)-3-bromo-carbazole and 9-(2',3'-epoxypropyl)-3, 6-dibromo-carbazole has been made.The proton noise decoupled, proton off-resonance decoupled and 13C-1Hcoupled NMRspectra for five carbazole derivatives are measured. The 13C NMRspectra data of them are analysed and compared. The following, points are summarized: (1) assignment methods of the resonance signals in13C NMR; (2) chemical shift range of epoxypropyl; (3) the range of coupling constants. The points described may be useful for determining valence bond characteristic and structure of these compounds.The experimental results show that carbon-13 chemical shifts, one-bond coupling and two-bond coupling constants of carbazole derivatives have fixed regularity. Therefore, they not only provide a powerful basis for determining structure but also bear some significance for study of 13C NMRof carbazole derivatives and complexes.
