In the present paper, the indentification of silver centers was improved and extended by the use of the single silver isotope .Ag. While the use of a single isotope is obviously limited

It comprised Raman scattering (1–8 inclusive), infrared absorption (1), spectroscopic calculations (9), viscosity (1, 10), thermal expansion (1, 11), electrical conduction (1, 12), and density and refractive index measurements (1, 13).

Measurements are given in the present paper span for lithium, sodium, and potassium borate glasses. However, we will emphasize the linkages of the structural units and have something to say

This study was undertaken to elucidate the coordination of boron in such glasses by recording and analyzing the infrared (IR) and Raman (R) spectral details that appear as a result of the incorporation of small amounts of boron.

Aside from its usefulness in the determination of N4, the fraction of four coordinated boron atoms, B-11 NMR has been of limited value in determining the coupling constant (Q.) and the asymmetry parameter (n) found in the glass. This limitation is due primarily to the importance of

Darrell R. Stokes,Charles R. Morganre. It also complicates the manner in which the structure can itself be conveniently and concisely described. Because of these difficulties it is necessary to apply all of the available experimental and theoretical techniques to the solution of this problem. The presence of a quadrupole moment at it
