CONTINUITIES IN SPECTRA AND STRUCTURE OF ACTINYL IONS

The band positions of the uranyl absorption spectrum have been diagramed to indicate the relative energy levels of the nonbonding orbitals for a molecular orbital model for the uranyl ion which has been defined as the actinyl core. The band positions of the transuranium actinyl spectra have been compared with the spacings between the positions of the uranyl bands. The results indicate that a single molecular orbital model can represent any of the actinyl ions when the uranyl ion is assumed to have the bonding orbitals exactly filled, and the transuranium actinyl ions are represented with the actinyl core and a progressive increase of electrons in the first two orbitals lying above the bonding orbitals. © 1969.
