High magnetic field and high spinning frequency one- and two-dimensional one-pulse MAS 19F NMR spectra of
fchars/beta2.gif" BORDER=0 ALIGN="middle">-ZrF4 and CeF4 were recorded and reconstructed allowing the accurate determination of the 19F chemical shifttensor parameters for the seven different crystallographic fluorine sites of each compound. The attributions of theNMR resonances are performed using the superposition model for 19F isotropic chemical shift calculation initiallyproposed by Bureau et al. (Bureau, B.; Silly, G.; Emery, J.; Buzaré, J.-Y. Chem. Phys. 1999, 249, 85-104). Asatisfactory reliability is reached with a root-mean-square (rms) deviation between calculated and measured isotropicchemical shift values equal to 1.5 and 3.5 ppm for fchars/beta2.gif" BORDER=0 ALIGN="middle">-ZrF4 and CeF4, respectively.
