Tanabe-Sugano Diagrams
• Both high and low spin complexes
• All terms are shown on diagram, spin forbidden transitions are
also shown
• Ground state is taken as constant reference and energies of all
other terms are plotted wrt ground terms
,Ground state term
symbols
, Symmetry Labels for Configurations
Free ion terms split into states in the ligand field, according to symmetry:
The state labels also indicate the degeneracy of the electron configuration:
