Description
Inorganic nanostructures reveal a number of applications in electronics, magnetic recording, as low-friction and nano-bio materials. However, our knowledge about properties of inorganic nanomaterials is still limited. Quadrupolar perturbed NMR is an excellent tool in studying the local site symmetry, chemical bonding and electronic structure of inorganic nano-particles comprising quadrupole nuclei. I will review my own and literature data on NMR spectra and relaxation measurements of quadrupole nuclei in several inorganic nano-compounds such as boron nitride nanotubes, vanadium oxide nanotubes and molybdenum sulfide fullerenes. Detailed analysis of the spectra and their comparison with those in bulk samples will be done. The obtained findings allow us making conclusions about the local crystal structure, electronic structure and bonding in the inorganic nanosized compounds.
