Název v původním jazyce

Raman and infrared study of phyllosilicates containing heavy metals (Sb, Bi): bismutoferrite and chapmanite

Popis výsledku v původním jazyce

The kaolinite-like phyllosilicate minerals bismutoferrite and chapmanite have been studied by Raman spectroscopy and complemented with infrared spectra. Tentatively interpreted spectra were related to their molecular structure. The antisymmetric and symmetric stretching vibrations of the Si-O-Si bridges, delta SiOSi and delta OSiO bending vibrations, nu (Si-O-terminal) stretching vibrations, nu OH stretching vibrations of hydroxyl ions, and delta OH bending vibrations were attributed to the observed bands. Infrared bands in the range 3289-3470 cm-1 and Raman bands in the range 1590-1667 cm-1 were assigned to adsorbed water. O-H ... O hydrogen-bond lengths were calculated from the Raman and infrared spectra.
