摘要

High-resolution solid state NMR spectroscopy of quadrupolar nuclei (preferentially ~(11)B and ~(27)Al) has been employed to study the micro structure of glasses. Importance has been attached to the extraction of the fundamental NMR parameters like chemical shift, quadrupole coupling constant etc., from the spectra, first of all by applying satellite transition spectroscopy. Exemplary results are represented for ternary oxide glass systems such as K_2O-Al_2O_3-SiO_2, B_2O_3-Al_2O_3-P_2O_5, Na_2O-B_2O_3-SiO_2 and Na_2O-B_2O_3-Al_2O_3.
