Al quadrupole nutation NMR provides valuable information on the structure of amorphous aluminosilicates derived from zeolite Y by chemical treatment. The local Al environment, ofwhich several kinds can be resolved in the two spectral dimensions, depends vitally on the mode of preparation of the samp
## Abstract The spatial ordering of aluminum atoms in CsAl(SiO~3~)~2~ and 3Al~2~O~3~Β·2SiO~2~ was probed by ^27^Al dipolar solidβstate NMR spectroscopy. The ^27^Al response to a Hahn spinβecho pulse sequence in a series of aluminumβcontaining model crystalline compounds demonstrates that quantitativ
