| A simple phenomenological model for the electric dipole intensities of nf → nf transitions is proposed. The model is derived by adopting of the common angular overlap model to the generalized Judd-Ofelt theory of the static coupling mechanism. It leads to reduction of a number of the effective intensity parameters to six, three of which correspond to the f → d excitations and the remaining to the f → g ones. Calculations performed for some lanthanide complexes show that the model, despite its inborn crudeness, provides satisfactory results and may be a convenient tool for a preliminary estimation of intensities. Regularity of the obtained parameters indicates a possibility of further reduction of their number. |
