摘要：
Silicon‐29 MAS (9 kHz) NMR spectra at 11.7 T, combined with an improved deconvolution procedure, are used to refine the Qn/Qn‐1 distribution model for binary glasses x Na2O · SiO2 (0.18 < x < 0.49). Using the fictitious temperature concept the binary distribution is shown to be the low‐temperature limiting case for the distribution of structural units Qn, Observed deviations from the strict model tending to random distribution can be explained by the model of Dorfeld. Additional structural information can be derived from 29Si chemical shift and line‐width data. Copyright © 1990 John Wiley & Sons, Ltd.
