The x-axis in a Tanabe-Sugano diagram is in terms of the crystal field splitting parameter, 10Dq, or Δ oct, scaled by the B Racah Parameter. The y-axis is in terms of energy of a electronic transition, E, scaled by B. Each line represents the energy of an electronic state while varying the strength of octahedral ligand field.. d7Tanabe-Sugano Diagram E / B ∆o/ B 4F 2G 2Eg 2T1g 2A1g 2T2g 4P 4A2g 4T1g (4P) 4T2g 4T1g (4F) small ∆o High Spin large ∆o Low Spin Complexes with d4-d7 electron counts are special •at small values of ∆o/B the diagram looks similar to the d2diagram •at larger values of ∆o/B, there is a break in the diagram leading to a new ground.

Lecture 4 May 11: Tanabe Sugano Diagrams A Tanabe-Sugano (TS) diagram plots the energy dependence of the various ligand field states (or terms) with field strength. The strength of the ligand field is defined by Dq, which is related to the octahedral crystal field splitting by 10Dq = ∆o. The energy of the state is given by E.. In coordination chemistry, Tanabe-Sugano diagrams are used to predict absorptions in the ultraviolet (UV), visible and infrared (IR) electromagnetic spectrum of coordination compounds.The results from a Tanabe-Sugano diagram analysis of a metal complex can also be compared to experimental spectroscopic data. They are qualitatively useful and can be used to approximate the value of 10Dq.
