| Nuclear magnetic resonance, NMR, continues to be a leading tool for elucidating the molecular structure of chemical systems. For systems where the solid phase structure is relevant, solid-state NMR can offer high resolution spectra. In addition, solid-state experiments can provide complimentary information through the measurement of anisotropic properties. This contribution will demonstrate solid-state NMR for two systems, polyaromatic hydrocarbons and polysaccharides. C-13 Chemical shielding anisotropy will be the primary NMR interaction of focus. The influence of structural features, i.e. extended aromaticity and the mutarotation of anomers, on the chemical shielding as well as the three individual principal components will be discussed. The high resolution techniques of magic-angle-spinning and cross-polarization will be explained. |
