Interpretation du Spectre RMN de l'Octaacetate de Cellobiose a 250 MHz. Application au Triacetate de Cellulose

Using a 250 MHz NMR spectrometer and double resonance experiments the full identification of the 14 cyclic protons of α octaacetate cellobiose has been performed. The results obtained here are of particular interest as affording an answer to the problem of the existence of particular signals in the NMR spectra of cellulose triacetate. These signals are both due to the anomeric extremity of the polymer.
