The free acids and sodium salts of a series of sulphonated azobenzene dyestu †s were examined in the solid and solution states by 13C and 15N NMR spectroscopy. In solution the spectra of both the free acids and salts are characteristic of trans-azobenzene structures, as are the spectra of the solid

77Se cross-polarization magic angle spinning (CP/MAS) and 13C CP/MAS experiments were employed to study the structure and dynamics of DL-selenomethionine (1) and L-selenomethionine (2) in the solid state. The 77Se principal elements of chemical shift tensors and shielding parameters for both compoun
## Abstract The composites formed by sugarcane bagasse and thermoplastic polymers, such as polypropylene (PP), polyethylene (PE), and ethylene‐__co__‐vinyl acetate (EVA), have been analysed by carbon‐13 high‐resolution solid‐state nuclear magnetic resonance (NMR), employing crosspolarization magic
