High-resolution two-dimensional Al-27 spin diffusion NMR spectra of 9Al(2)O(3) (.) 2B(2)O(3) 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. (c) 2006 Elsevier B.V.
