Oxygen-17 multiple-quantum magic-angle spinning and double rotation nuclear magnetic resonance studies were performed in the field of 17.6 T. A correlation between the isotropic value of the chemical shift and the SiOAl bond angle in zeolites was found. The correlation may be used for the determination of bond angles in SiOAl sites without long-range order. It is shown that multiple-quantum and double rotation techniques are complementary tools for getting highly-resolved O-17 NMR Spectra of solids. (C) 1998 Elsevier Science B.V. All rights reserved.
