Vibrational Spectra of Transition Metal Hexafluoride Crystals. III. Exciton Band Structures of MoF6, WF6 and UF6.
Abstract
This paper presents the overall vibrational band structure of MF6 crystals based on the previously discussed two-particle, heavily doped mixed crystal, and neat crystal data in addition to dilute mixed crystal studies. Calculations of nu(2) and nu(5) bands based on a quadrupole-quadrupole intermolecular interaction model are determined to be in substantial agreement with the observations. The nu(1) bands are discussed in detail for a series of concentration studies and it is possible to demonstrate that MoF6 and WF6 conform to the ideal mixed crystal model whereas crystals containing UF6 do not. A consistent picture of gas-to-crystal shifts, resonance interactions, band shapes and structures, densities of exciton states, Fermi resonance, and simple multipolar interaction models emerges from these studies.
