Solid state effects in the electronic structure of TiCl4 studied by XPS

High resolution x-ray photoelectron spectra of TiCl4 have been obtained in the solid state. Core levels, their shape-up satellites and valence levels are described and discussed in detail. From comparison with gas phase XPS data, UPS spectra, and theoretical models from the literature, emerge specific characteristics of this molecular solid. Special attention is paid to peculiarities of chlorine orbitals, which are discussed in the light of similar data for organic and inorganic chlorides.
