Possibilities and limitations of iterative lineshape fitting approaches for the complete determination of magnitudes and orientations of NMR interaction tensors in a four-13 C-spin system from MAS NMR experiments are investigated. The availability of fast and numerically accurate computational metho

The spinning sidebands observed in the 13 C MAS NMR spectra (Fig. 1a), oriented in a nematic phase and in the solid state of cis,cis-mucononitrile oriented in liquid-crystalline media and of are presented. As a consequence of the carbon-13 chemicalthe neat sample in the solid state are studied. Ther
The orientations of the 13C chemical shift tensors in undoped cis-and tram-polyacetylene have been determined from the chemical shift-dipolar two-dimensional powder patterns observed in rotating samples.
## Abstract A combination of solidβstate ^13^C CP/MAS NMR methods was used to study the rates of rotation of the phenyl group in 3,5βdimethylβ1βphenylhexβ1βynβ3βol. The methods used were __T__~1Ο~ measurements, lineshape analysis and 2D exchange spectroscopy over the temperature range 219β284 K. Th
