Orgel Diagramm. Orgel diagrams d f p orgel diagrams are only for high spin complexes showing only the spin allowed transitions relative to some parent ground state free ion term p d or f. The horizontal axis is the size of the ligand field splitting energy delta o.
Follow me on unacademy. In orgel diagrams the magnitude of the splitting energy exerted by the ligands on d orbitals as a free ion approach a ligand field is compared to the electron repulsion energy which are both sufficient at providing the placement of electrons. However if the ligand field splitting energy 10dq is greater than the electron repulsion energy then orgel diagrams fail in determining electron placement.
These are separated as the d and f p orgel diagrams.
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 horizontal axis is the size of the ligand field splitting energy delta o. For complexes with d ground terms only one electronic transition is expected and the transition energy corresponds directly to d. However if the ligand field splitting energy 10dq is greater than the electron repulsion energy then orgel diagrams fail in determining electron placement.
