A cellular ligand-field model for ‘l-l’ spectral intensities

Abstract

The model for the reproduction of the intensity distributions within ligand-field d-d spectra, presented in the preceding paper, is applied here to 24 chromophores. Eight have approximate tetrahedral geometry, five are trigonal bipyramidal, and eleven are trigonally distorted octahedra. All intensity analyses rest on prior ligand-field analyses which are collected together here, some being reported for the first time. Good reproduction of relative intensities has been achieved for all the four- and five-coordinated complexes and for none of the six-coordinate. It is presumed that the intensities of these latter species are dominated by vibronic mechanisms.
