N2 - We have obtained the solid-state oxygen-17 nuclear magnetic resonance spectra of the group IIA and group IIB oxides (BeO, MgO, CaO, SrO, BaO, ZnO, CdO, and HgO) using high-field (8.45 and 11.7 T) static and "magic-angle" sample-spinning techniques. The results indicate a chemical-shift range of more than 600 ppm for the group II oxides, and a range of oxygen-17 nuclear quadrupole coupling constants (e2 qQ h) from ∼0 (CaO, SrO, BaO) to about 7 MHz (for HgO). The chemical shifts observed for the group IIA oxides are well fitted by an equation of the form δ (ppm, from H2O) = 257r3 ( A ̊3) + 11, where r is the ionic radius of the metal cation. The e2 qQ h values increase with increasing metal electronegativity and thus decrease on descending group IIA, but increase on descending group IIB.
