Abstract:

A new experimental technique is described whereby the soft x-ray CrLIII, 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.
