“…As reported previously, 40 Al sites with a strong distortion of the symmetry are "NMR-invisible". The preferential H2 chemisorption sites are thought to be H2-accesible ¼ -As one possible highly distorted unoccupied site (denoted as Alun), we suggest a pseudo three-coordinated Al site stabilized by weekly coordinated two N^ ligands within the SiAlN amorphous network shown in the following proposed reaction scheme for H2 chemisorption (Fig.…”

“…The peak at 110.0 ppm was observed in both SL and BM composites, which is similar to a [AlN4] environment (115 ppm). 28 Therefore, this peak would be attributed to Thus, these peaks could be corresponding to amorphous Al-N-B-H phase. As shown in Fig.…”

Abstraer. There have been great improvements in the quality of 27A1 NMR spectra from solids over the last decade. The impact of this technique on structure determination fora wide range of solids is briefly reviewed. Emphasis is placed on the effects arising from the presence of the quadrupolar interaction and strategies that allow unambiguous spectral interpretation. It is demonstrated that in addition to the chemical shift, the quadrupolar interaction itself can be a rich source of local information about solids. The insight obtalned from 27A1 NMR hato atomic level structure often contains surprises, such that previous models of structure and properties have to be reassessed.
