How do you read tanabe-sugano diagram?

Answer 1

A Tanabe-Sugano diagram is used to predict the energy levels of d-orbitals in transition metal complexes based on their oxidation states and ligand field strength. The vertical axis represents the energy of the d-orbitals, while the horizontal axis indicates the ligand field strength, often expressed as a ratio of the crystal field splitting energy (Δ) to the pairing energy (P). Different curves correspond to various electron configurations of the metal ion, showing how the energy levels change as the ligand field strength varies. By locating the appropriate curve for a specific metal-ligand combination, you can determine the splitting pattern and the expected electronic transitions.
