Abstract
Raman spectra were obtained for single- and polycrystalline specimens of some oxide compounds used as quantum electronic materials and for native minerals containing complex anions, where the cations are alkaline-earth metals and lead. An analysis of the low-frequency regions of the Raman spectra showed that, in some cases, the pair of high-intensity lines appearing in the range below 100 cm–1 serves as an indicator of the presence of Pb2+ ions.
