One-dimensional - P NMR is only able to probe the the local structure of phosphate glasses. To gain information about the manner in which the different Q units or domains in phosphate glasses are connected, two-dimensional MAS exchange experiments have been used in which radio-frequency dipolar recoupling (RFDR) techniques allow the reintroduction of the through-space dipolar-dipolar interaction even [Pg.442]

The application of P NMR to structural studies of alkali and alkaline earth phosphate and aluminophosphate glasses, fluorophosphate glasses and phosphorus oxynitride glasses has been reviewed by Kirkpatrick and Brow (1995). [Pg.443]

Both Li and Li MAS NMR has been used to investigate the local Li coordination environment in a series of binary lithium phosphate glasses (Alam et al. 1999). The Li chemical shifts, which approximate closely to the isotropic chemical shifts, increase... [Pg.638]

An analogous approach has been applied to a number of binary and ternary phosphate glasses, resulting in very insightful quahtative and quantitative information [67-77]. First of all, the observation of crosspeaks in 2D-exchange, RFDR, as well as DQ-ejqjeriments unambiguously reveal the occurrence of Q< >-and Unkages. [Pg.224]

Analysis, under high resolution, of the SrO emission spectrum yielded the following vibrational wavenumbers SrO 654.4774956 cm SrO 653.8864510 cm and SrO 653.30998 cm . Raman spectroscopy was used to characterise the binary strontium phosphate glasses, xSrO.(100 — x)P20s, where 0.5 > x > 0. There were signihcant differences from the calcium analogues. ... [Pg.191]
