High-resolution two-dimensional 27Al spin diffusion NMR spectra of 9Al2O3 Æ 2B2O3 recorded under double rotation for different mixing times are presented. The two crystallographically distinct pentahedral Al sites are distinguished by the presence or absence of correlation peaks with neighboring tetrahedral sites.
