Paper Abstract

Particularly pure samples of titanium dioxide with a different crystalline structure and a different construction of TiO2 polycrystaline particles which were produced by thermal hydrolysis of TiCl4 hydrochloric acid solutions, were studied by methods of IR and Raman spectroscopy. The assignment of IR and Raman spectral bands to vibrations of different symmetry types has been performed. In accordance with positions and half-width of Raman lattice vibrational band 'ν=143 cm-1'. The stoichiometric composition estimation of TiO2 different crystalline phases has been carried out according to data obtained about the position and half-width of the lattice Raman vibrational band. The intensity and frequency of IR bands in the region of 1250-900 cm-1 were shown to be sensitive to a type of TiO2 crystalline composition and to the physically adsorbed water content.
