| Summary: | Ligand field theory of d^3 transition metal ions in cubic and quadrate fields is briefly summarized, along with the features of the predicted spectra. Diffuse reflectance spectra of a variety of quadrate chromium(III) complexes are measured with special emphasis on uncovering the component structures of the spin-forbidden transitions. Energy level assignments are made for components of both spin-allowed and spin-forbidden bands by fitting of the calculated and observed energy levels. Electron correlation and ligand field parameters are derived by the fitting procedure, and the usefulness of the repulsion parameters Band C in bonding considerations is discussed. Results reveal the need for certain refinements of the present state of ligand field theory. The need for improved experimental techniques to provide more precise and abundant spectral data is evident. When more data is available it will be possible to continue the extensions of the theory of ligand fields to s ystems of lower symmetries. | |
