abstract

Using the method of Fourier spectroscopy, the IR absorption and reflection spectra were obtained in the frequency region 240 divided by 5000 cm-1 for different types of high- purity silica glasses (v-Sao2), containing from 0.1 to 103 ppm of the hydroxyl groups OH. The analysis of the positions of both the fundamental structural band (v approximately 1120 cm-1) monitored in IR reflection mode and an overtone of this band (v approximately 2260 cm-1) monitored in IR transmission mode was carried out for various as-received silica glasses and their fictive temperatures were determined. On the basis of the classical dispersion analysis the absorption band parameters and the spectra of optical constants ((epsilon) ', (epsilon) '', n and k) were calculated for vitreous Sao2.
