Glasses in the system xB 2 O 3 Á ð1 À xÞSiO 2 ð0:2 x 1:0Þ were studied using 11 B multiple quantum magic angle spinning NMR spectroscopy (MQMAS), 29 Si-f 11 Bg rotational echo adiabatic passage double-resonance and 29 Si-f 11 Bg CP heteronuclear correlation spectroscopy. The results can be quantita
EPR absorption spectra of Cu 2 + were investigated in vitreous matrices of the system [70TeO2-25B2Os-5PbO] over a wide range of concentrations. The detected absorptions are strongly dependent on the matrix composition. Fluctuations of the ligand field were evident in the Cu 2 § environment. The conc
