Inner shell spectroscopy of (η5-C5H5)2TiCl2, (η5-C5H5)TiCl3, and TiCl4

Abstract

Oscillator strengths for C 1s excitation of gas phase Cp2TiCl2 and CpTiCl3 (Cp = η5-C5H5), and Cl 2p and Ti 2p excitation of gas phase Cp2TiCl2, CpTiCl3, and TiCl4 have been derived from electron energy loss spectra recorded under electric dipole scattering conditions. The C 1s spectra are interpreted with the aid of semiempirical extended Hückel calculations and comparisons with the C 1s spectra of other cyclopentadienyl complexes. The Ti 2p spectra are interpreted using the extended Hückel results and comparisons with atomic multiplet–crystal field calculations for Ti4+ taken from the literature.
