| Popis: | Influence of the covalence, octahedral distortion and the translation symmetry of the chromium ions in octahedral coordination on the electronic structure for compounds under investigation was clarified. Cr L 2,3 and Ti L 2.3 X-ray absorption spectra (XAS) along with atomic multiplet calculations and resonant Ti 2p-3d and Cr 2p-3d photoelectron spectra of valence band (RXPS) in the intercalated titanium dichalcogenides Cr x TiX 2 (X = Se, Te) and in the substitution compound Ti x Cr 1− x Se 2 show the charge transfer between chromium and titanium sublattices. |
