Aluminum-27 Double Rotation NMR spectroscopy (DOR) has been used to investigate framework ordering in the aluminophosphate molecular sieves VPI-5, AlPO{sub 4}-5, and AlPO{sub 4}-8. Well resolved peaks in the {sup 27}Al 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 {sup 27}Al DOR spectra of AlPO{sub 4}-5 and AlPO{sub 4}-8.
