✦ Synopsis

Ž 13 . Solid-state Cross-Polarization Magic Angle Spinning Carbon-13 Nuclear Magnetic Resonance CPrMAS C-NMR has been used to investigate the structure and interactions of cellulose I. The use of spectral fitting for the extraction of information from CPrMAS 13 C-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.

## Abstract In order to obtain some insight into the structure of an ultrahigh‐molecular‐weight polyethylene sample, ^13^C CP/MAS NMR experiments have been carried out at temperatures from 23 to −108°C. The peak for the crystalline component moves upfield with a decrease in temperature, which is co

## Abstract ^15^N and ^13^C chemical shifts and the ^1^__J__(^15^N^15^N), ^1^__J__(^15^N^13^C) and ^1^__J__(^13^CH) coupling constants have been determined for a number of ^15^N‐enriched cyclic and acyclic secondary nitramines. The results are interpreted in terms of both electronegativity effects
