✦ Synopsis
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.
