They are qualitatively useful and can be used to approximate the value of 10Dq, the ligand field splitting energy. Tanabe-Sugano diagrams can be used for both high spin and low spin complexes.
Visualizing the 3F and 3P States (see Table ) 3F is the ground state with 21 microstates • One electron into each orbital places them as far apart as possible • For these seven orbital combinations remember that there will be M S = +1, 0, –1 microstates 3P is the spin-allowed excited state with 9 microstates • These microstates put the electrons in the same plane, resulting in greater. use the appropriate Tanabe-Sugano diagram to locate where the ratio of the second to first peak matches that found experimentally.
Tabulate the values of ν 1 /B’, ν 2 /B’, ν 3 /B’ from the Y-intercepts and Δ/B’ from the X-intercept. 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.
