This two-dimensional experiment separates the chemical-shift powder patterns of the phosphorus sites according to their isotropic chemical shifts. We have thus determined all chemical-shift tensor elements for each chemically distinct phosphorus site in these glasses, and their variation within each site. Our results yield a precise description of the phosphate types and geometries in these glasses.article472114618Copyright 1993 The American Physical Society
