Schwingungsspektren von komplexen Boraten.

Abstract

The aim of the investigations was the characterization of the polyborates, as far as IR-spectroscopy is concerned. The investigations covered the absorption spectra of different pentaborates, including those substituted by 10B-, 11B-, and H-D-isotopes, as well as the reflection spectra of potassium-pentaborate single crystals with polarized radiation. The concept of group frequency analysis was successfully applied to the interpretation of the pentaborate-spectra; almost all bands were attributed to vibrations of the BO3, BO4 and OH units.
