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.

Notes on d7 Tanabe-Sugano Diagram!The d 7 diagram, like all such diagrams for configurations that may be either high spin or low spin, has a perpendicular line near the middle marking the change in spin state. "To the left of the line (low field strength, high spin), the ground state is 4T 1, emerging from the free-ion 4F term.

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=17400 cm-1, ν2=25400 cm-1 and ν3=34500 cm-1.

Print the appropriate Tanabe-Sugano diagram and locate where the ratio of the second to first peak matches that found experimentally. Tabulate the values of v1 / B, v2 / B, v3 / B from the Y-intercepts and Δ/B from the X-intercept. A laboratory experiment based on this is described in more detail in the CHEM2110 lab manual.
