One dimensional 17O MAS NMR along with multiple quantum MAS NMR has been used to identify at least three different oxygen sites, including the bridging oxygens (BO) and two different terminal oxygens (TO), in the hexagonal (h) crystalline form of P217O5. The 17 O MAS NMR spectrum from v-P217O5 reveals that a distribution of oxygen environments are present, such that the BO and TO are not resolvable under simple MAS.
