摘要：

V-51 MAS NMR spectra exhibiting the complete manifold of spinning sidebands (SSBs) from all seven V-51 (I = 7/2) transitions have been observed for NH4VO3 and V2O5. These spectra are influenced by interactions from both V-51 quadrupole coupling and chemical-shielding anisotropy. A simulation and iterative-fitting program which allows the first determination of quadrupole and anisotropic shielding tensors, including the relative orientation of their principal-axis systems, from MAS NMR spectra is introduced. The V-51 parameters determined from the SSB intensities for NH4VO3 and V2O5 are compared with literature data from static NMR spectra.
