, Orgel diagrams are correlation diagrams wh … Orgel diagrams are correlation diagrams which show the relative energies of electronic terms in transition metal complexes, much like Tanabe–Sugano diagrams. They are named after their creator, Leslie Orgel. Orgel diagrams are restricted to only show weak field (i.e. high spin) cases, and offer no information about strong field (low spin) cases. Because Orgel diagrams are qualitative, no energy calculations can be performed from these diagrams; also, Orgel diagrams only show the symmetry states of the highest spin multiplicity instead of all possible terms, unlike a Tanabe–Sugano diagram. Orgel diagrams will, however, show the number of spin allowed transitions, along with their respective symmetry designations. 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 two Orgel diagrams, one for d1, d4, d6, and d9 configurations and the other with d2, d3, d7, and d8 configurations. In an Orgel diagram, lines with the same Russell–Saunders terms will diverge due to the non-crossing rule, but all other lines will be linear. Also, for the D Orgel diagram, the left side contains d1 and d6 tetrahedral and d4 and d9 octahedral complexes. The right side contains d4 and d9 tetrahedral and d1 and d6 octahedral complexes. For the F Orgel diagram, the left side contains d2 and d7 tetrahedral and d3 and d8 octahedral complexes. The right side contains d3 and d8 tetrahedral and d2 and high spin d7 octahedral complexes. d2 and high spin d7 octahedral complexes.

Questi diagrammi prendono il nome da Leslie Orgel, che li introdusse nel 1952. I diagrammi di Orgel si limitano a trattare complessi a campo debole (cioè specie ad alto spin) e non si possono applicare ai casi a campo forte (basso spin). I diagrammi di Orgel danno solo informazioni qualitative, comunque utili a prevedere il numero di bande presenti nello spettro di assorbimento, indicando la simmetria degli stati elettronici coinvolti. Non permettono invece di determinare il valore di Δo, né di trattare le transizioni proibite per spin. Tali informazioni quantitative si possono invece ottenere dai diagrammi di Tanabe-Sugano, che sono applicabili a tutti i tipi di complessi (a campo sia forte che debole) e permettono di discutere anche le transizioni proibite per spin. Esistono due diagrammi di Orgel, uno per ioni che hanno termine spettroscopico D e uno per quelli che hanno termini spettroscopici F e P.li che hanno termini spettroscopici F e P.

Orgel-Diagramme sind auf high-spin Komplexe beschränkt und bieten keine Informationen über low-spin-Komplexe. Da die Diagramme qualitativ sind, können aus diesen Diagrammen keine Energieberechnungen durchgeführt werden. Auch zeigen Orgel-Diagramme im Gegensatz zu einem Tanabe-Sugano-Diagramm nur die Symmetriezustände der höchsten Spin-Multiplizität anstelle aller möglichen Terme. Orgel-Diagramme zeigen jedoch die Anzahl der Spin-erlaubten Übergänge zusammen mit ihren jeweiligen Symmetriebezeichnungen. In einem Orgel-Diagramm befindet sich der Hauptterm (P, D oder F) in Abwesenheit eines Ligandenfeldes in der Mitte des Diagramms. Es gibt zwei Orgel-Diagramme, eines für die Konfigurationen d1, d4, d6 und d9 (D-Orgel-Diagramm) und das andere für die Konfigurationen d2, d3, d7 und d8 (P- und F-Orgel-Diagramm)., d3, d7 und d8 (P- und F-Orgel-Diagramm).
