TanabeSugano. A python-based Eigensolver for Tanabe-Sugano- & Energy-Correlation-Diagrams based on the original three proposed studies of Yukito Tanabe and Satoru Sugano for d 2-d 8 transition metal ions:. On the Absorption Spectra of Complex Ions. A series of JAVA applets of Tanbe-Sugano diagrams were developed by Prof. Robert Lancashire at the University of the West Indies. These diagrams allow students to determine delta o /B values based on ratios of peak energies without the pain of rulers and drawing lines. There are also features that allow a person to input values and automatically calculate certain parameters.

2 • Tanabe-Sugano diagrams have been calculated for d the cases of all ligand field strengths for all octahedral dn-metal complex configurations. • The diagrams allow for estimation of a complete set of parameters included in the calculations: i) the (apparent) electron repulsion parameter B', ii) D, iii) transition frequencies.

Tanabe-Sugano diagrams are used in coordination chemistry to predict electromagnetic absorptions of metal coordination compounds of. The different free ion terms for an electron configuration have different energies due to variations in electron-electron repulsion. The different. Tanabe-Sugano diagrams do not have this restriction and can be applied to the situations when Δ is significantly greater than inter-electronic repulsion. Thus, the Tanabe-Sugano diagrams can be utilized in determining electron placements for high-spin and low-spin metal complexes. Tanabe-Sugano Diagram - Parameters Parameters The x-axis of a Tanabe–Sugano diagram is expressed in terms of the ligand field splitting parameter, Dq, or Δ, divided by the Racah parameter B. The y-axis is in terms of energy, E, also scaled by B. Three Racah parameters exist, A, B, and C, which describe various aspects of interelectronic repulsion.

TANABE-SUGANO DIAGRAMS. Tanabe-Sugano diagrams show both low-spin and high-spin cases, and also show spin-forbidden transitions. They even show terms that are near to, but not the ground state! Also, as previously mentioned, there is a hole formalism that says that a dn diagram for octahedral complexes applies to d10−n tetrahedral complexes.
