Central field expansion of radial integrals derived from ligand field parameters
The uses of the previously introduced “United Atom” diagrams of certain transition metal complexes are extended. In particular it is shown that with the help of existing expansions of the ligand field parameters DQ, λ, B, etc. in terms of neff and Zeff these diagrams can be successfully used to predict trends and variations in these parameters. The predicted trends and variations are then compared to experimental data.
