Soft X-Ray Band Spectra and Molecular Orbital Structure of Cr2O3, CrO3, CrO4(-2), and Cr2O7(-2)

Abstract

A new experimental technique is described whereby the soft x-ray CrL(III), CrK, and OK emission and absorption spectra are combined and used to construct empirically a complete molecular orbital diagram for simple chromium- oxygen compounds. All spectral components are assigned specific transitions associated with bonding, antibonding and nonbonding molecular orbitals. Relationships between the x-ray spectra and various solid state phenomena such as coordination symmetry, bonding distances, valence state, and bonding character are discussed. It is concluded that the x-ray band spectra from compounds are best interpreted on the basis of molecular orbital theory.
