Orgel Diagram. This video shows how we can interpret orgel diagrams for metal ions in octahedral tetrahedral field other related videos molecular orbital approach to tran. These are separated out into one d diagram and one f p diagram.
Orgel diagrams are correlation diagrams which show the relative energies of electronic terms in transition metal complexes much like tanabe sugano diagrams. Orgel diagrams and predicting electronic transitions in transition metal complexes. Orgel diagrams are correlation diagrams that correlate orbital energies as they vary with ligand field strengths consider the ground atomic state and examine what happens in the weak field limit i e.
The simple correlation diagram had multiples of b the racahparameter on the energy axis to denote the relative energies of the atomic terms.
They only show the spin allowed transitions. Each tanabesugano diagram is given for only one specific b c ratio the best value. Orgel diagrams are useful for showing the energy levels of both high spin octahedral and tetrahedral transition metal ions. Orgel diagrams are correlation diagrams which show the relative energies of electronic terms in transition metal complexes much like tanabe sugano diagrams.
