title: Refinement of solid-state MAS NMR spectra of quadrupolar nuclei: application to the analysis of some 51V compounds.
abstract: Magic angle solid-state 51V NMR spectra of several vanadium powder compounds have been recorded. A refinement of these spectra using theoretical simulations of the powder spectra have been performed assuming the simultaneous anisotropic effects of electric field gradients (EFG) and of electronic shielding. It is shown that the relative orientation of the principal axes of the two tensors have to be considered.
