Using three fluorinated steroids as examples, it is demonstrated that for simple multi-fluorinated organic molecules single-pulse and cross-polarization magic-angle spinning experiments with proton decoupling are both feasible and informative. Spinning sideband manifolds are used to obtain shielding
ReceiM?d 6 September '1971 Measurement of the lgF NMR frequency versus orientation in single crystals of fluorapatite C&F(FO4)3 about two perpendicular crystal axes has allowed determination of all principal amponents of the nuclear saeenix tensor, which was found to be axially symmetric with uu -o1
Local environment of fluorine atoms in the lanthanum oxyfluoride aluminosilicate glasses and glassceramics modified by SrO was studied by solid state 19 F MAS-NMR spectroscopy and X-ray diffraction. The effect of strontium concentration on the formation of crystalline LaF 3 phase was determined, as
