Abstract

Aluminum-27 Double Rotation NMR spectroscopy (DOR) has been used to investigate framework ordering in the aluminophosphate molecular sieves VPI-5, AIPO₄-5, and AIPO₄-8. Well-resolved peaks in the ²⁷Al DOR spectra of both hydrated and dehydrated VPI-5 allow isotropic shifts to be correlated with local framework structure. More distorted aluminum environments are reflected by broader lines in ²⁷Al DOR spectra of AlPO₄-5 and AlPO₄-8.
