dc.description.abstractThe vibrational spectroscopic methods were used to study the Si-O bond character in silicates with different complex anions and crystal structures. The following calcium silicates were examined: $Ca_{3} (Sio_{5}), \gamma - Ca_{2} ( Sio_{4}), \beta - Ca_{2} (Sio_{4}), Ca_{3} (Si_{2}o_{7}), Ca (Sio_{3}) \stackrel{1}{\infty}$ and $Ca_{3} (Si_{3}o_{9})$. The bond assignments in IR and Raman spectra of these compounds have been deduced mainly from $^{28} Si - ^{30}Si$ and $^{40} Ca - ^{44}Ca$ isotopic shifts. GF matrix methods and molecular approximation for force constant calculations in silicate anions have been used. The Si-O bond parameters such as: bond order, charge distribution and bond ionicity were obtained from calculated force constants. The nature of Si-O bonds with respect to complex anion and crystal structure will be discussed.en_US
