Orgel Diagram For D1. In this video lecture we will learn about the orgel diagrams. There are only two orgel diagrams one for d1 d4 d6 and d9configurations and the other with d2 d3 d7 and d8configurations.
D orgel diagram on the left hand side d 1 d 6 tetrahedral and d 4 d 9 octahedral complexes are covered and on the right hand side d 4 d 9 tetrahedral and d 1 d 6 octahedral. The section of orgel and tanabe sugano diagrams for transition metal complexes d1 d9 states from the chapter entitled electronic spectra of transition metal complexes covers the following topics. There are two orgel diagrams d f.
In an orgel diagram the parent term p d or f in the presence of no ligand field is located in the center of the diagram with the terms due to that electronic configuration in a ligand field at each side.
There are only two orgel diagrams one for d1 d4 d6 and d9configurations and the other with d2 d3 d7 and d8configurations. Orgel and tanabe sugano diagrams for transition metal complexes d1 d9states it is a well known fact that electronic transitions are always accompanied by vibrational as well as rotational changes which results in a considerable broadening of the bands in the uv visible spectra of transition metal complexes too. In an orgel diagram the parent term p d or f in the presence of no ligand field is located in the center of the diagram with the terms due to that electronic configuration in a ligand field at each side. The orgel diagram for a typical octahedral mathrm d 2 complex is shown below.
