We thank Dr. D. Rice (Varian) for recording the 27Al MQ MAS NMR spectra, and Dr. D. H. Olson (UPenn) and Prof. N. H. Heo (KNU) for providing the crystallographic data on two as-made ZSM-5 zeolites with Si/Al=86 and 300.

Gestützt werden diese Folgerungen durch simulierte Spektren (Beispiel siehe Bild) auf der Grundlage von Röntgenbeugungsdaten.
