Abstract
We investigated the electronic structures of the perovskite-type transition-metal oxides Mo, Ru, and Rh) using their optical conductivity spectra The interband transitions in are assigned, and some important electronic structure parameters, such as charge-transfer energy and crystal-field splitting are estimated. It is observed that and decrease systematically with increasing the atomic number of the transition metal. Compared with the case of oxides, the magnitudes of and are larger. These behaviors can be explained by the more extended nature of the orbitals in the oxides.
