Kurzbeschreibung (Abstract)
Five vanadium complexes as models for biological systems were investigated using V-51-MAS-NMR spectroscopy. All spectra show an uncommon line shape, which can be attributed to a shorter relaxation time of the satellite transition in contrast to the central one. A method for the reliable analysis of such kind of spectra is presented for the first time and the most important NMR parameters of the investigated complexes (quadrupolar coupling constant C-Q, asymmetry of the EFG tensor eta(Q), isotropic chemical shift delta(iso),chemical shift anisotropy delta(sigma) and asymmetry of the CSA tensor eta(sigma)) are presented. These results are of particular importance with respect to the analysis of the V-51-MAS-NMR spectra of vanadium moieties in biological matrices such as vanadium chloroperoxidase, which show hitherto unexplained low intensity of the satellite sideband pattern.
