Lecture 4 May 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. A Tanabe-Sugano diagram of the spin-allowed and some forbidden transitions for high spin octahedral d 7 complexes is given below.

The baseline in the Tanabe-Sugano diagram represents the lowest energy or ground term state. The d 2 case (not many examples documented). The electronic spectrum of the V 3+ ion, where V(III) is doped into alumina (Al 2 O 3), shows three major peaks with frequencies of: ν1= cm-1, ν2= cm-1 and ν3= cmFile:D7 Tanabe-Sugano schematron.org – Wikimedia CommonsCalculations using Tanabe-Sugano diagrams
