Abstract

Investigation of benzophenone (BP)-TiO₂ and 4-amyl-4'-cyanobiphenyl (5CB)-TiO₂ bicomponent mixtures by vibrational spectroscopy and quantum mechanical methods was carried out. IR spectra of BP-TiO₂ and 5C-BTiO₂ were measured in 400-3800 cm^-1 region. The structure, energy, electrooptical parameters, frequencies and IR intencities for the models of H-bond complexes which are seem to be formed in near surface layer of the TiO₂ nanoparticles, embedded into BP and 5CB samples. Calculations were performed using B3LYP/6-31+G(d) method.
