L. Visscher et Wc. Nieuwpoort, RELATIVISTIC AND ELECTRON CORRELATION-EFFECTS ON THE D-D SPECTRUM OF TRANSITION-METAL FLUORIDES, Theoretica Chimica Acta, 88(6), 1994, pp. 447-472
The electronic spectra of the transition metal complexes CoF62-, RhF62
- and IrF62- that occur in the solids CS2MeF6 are calculated. Hartree-
Fock and Dirac-Fock calculations followed by non-relativistic and rela
tivistic CI calculations respectively are used to study the influence
of relativity and electron correlation. The calculated transitions are
found to agree fairly well with experiment, the largest discrepancies
arising from the neglect of differential dynamical electron correlati
on effects.
