- Abstract
- Two crystallographically distinct tetrahedral Al sites in zeolite merlinoite are directly identified by ultra-high-field (18.8 T) (27) Al MAS NMR spectroscopy. The experimental chemical shifts and peak areas indicate a preferential siting of Al in site T-II. This non-random aluminum distribution is independently confirmed by ultra-high-field (18.8 T) (29) Si MAS NMR spectroscopy. (C) 2002 Elsevier Science B.V. All rights reserved.
