✦ Synopsis

We have investigated the optical conductivity spectra of [ Ru ( pzRu ) 4] m+ (pz = pyrazine ) , as representative of the whole class of linear mixed valence complexes of ruthenium, through a two-band Hubbard Hamiltonian. It is shown that the main features of absorption spectra, observed experimentally for various degrees of oxidation (m), are well reproduced within this simple model.
