Russian Federal Nuclear Center — All-Russia Research Institute of Experimental Physics, Sarov, Nizhny Novgorod Oblast, Russia aut Calculation-graphic analysis of the IR spectrum of a glass batch containing sodium borate and silicate and boric and silicic acids [Elektronische Daten] [E. Medvedev] A calculation-graphic analysis of the IR spectra of sodium borate and silicate as components of a glass batch, obtained in aqueous medium, and probable contaminants — boric and silicic acids — was conducted. It was found that several bands called critical coincide or are close together in the spectrum. Among them are the bands at 947-959, 1004-1005, 1079-1086, 1195-1200, 1450-1453, and 1686-1690 cm−1 characterizing the fundamental vibrations of the atoms in bonds in cross-linking groups, and they cannot be distinguished by either the wavenumber or the intensity so that it is impossible to identify the phases formed. The concept of "conditionally distinguishable bands” in the spectra of comparable substances was introduced. The absolute degrees of difference in the wavenumber and intensity, order of sorting the bands, and determination of the boundaries of the critical regions of the spectrum of the batch were examined.
