摘要：

Solid-state Cross-Polarization Magic Angle Spinning Carbon-13 Nuclear Magnetic Resonance (CP/MAS C-13-NMR) has been used to investigate the structure and interactions of cellulose I. The use of spectral fitting for the extraction of information from CP/MAS C-13-NMR spectra is reviewed and results obtained are discussed. Examples are shown where the method has been used to monitor the structural changes occurring in wood cellulose during kraft pulping. The effects observed on the cellulose and hemicelluloses are further investigated using a model system. Assignments of signal intensities originating from xylan-cellulose interactions are made.
