摘要
P-31 NMR CW and FT MAS measurements have been used to investigate the structural composition of x(MeO).(1 - x)(P2O5) glasses (Me = Ca, Sr, Ba, x = 0.25-0.50). The influence of the structural composition on components of the chemical shift tensors is determined and discussed by means of a correlation between isotropic chemical shifts in crystalline phosphates and molecular structure published recently by Sternberg et al. [Z. Phys. Chem. Neue Folge 168 (1990) 115].
