Vibrational interactions of tetrahedra in silicate glasses and crystals: III. Calculations on simple sodium and lithium silicates, thortveitite and rankinite
Differences between crystals and glasses in the number and location of main high-frequency ir peaks suggest short-range bonding rearrangements in glasses. (Crystallite models are not applicable.) Antisymmetrical mid-frequency ir modes occur in silicates more polymerized than the pyrosilicate. 40 ref...
