Question

Given the Tanabe-Sugano diagram below for a d3 complex.Which of the following transitions corresponds to the ∆o?
A.4A2g → 4T1g (F)
B. 4T2g → 4T1g (P)

C.4A2g → 4T1g (P)
D.4A2g → 4T2g
This graph represents the energy levels of a d^3 electronic configuration in a crystal field. The x-axis is labeled with the term \( ^4A_2 \) and extends from 0 to 40. The y-axis is labeled with \( ^4F \) at the origin and extends from 0 to 70.

There are four curves plotted on the graph, representing different electronic states:

1. The bottom curve starts at \( ^4F \) and increases steadily, maintaining a consistent curve to terminate at \( ^4P \) around an x-value of 10 and y-value of 20.
2. Above the \( ^4P \) curve, another curve labeled \( ^4T_2 \) increases more steeply, starting just above the lower curve in the lower section of the chart.
3. Continuing upwards, the next curve is labeled \( ^4T_1 \), starting below 10 on the x-axis and continuing with a steeper rise.
4. The topmost curve, also labeled \( ^4T_1 \), demonstrates a sharply increasing slope, starting a little rightward on the x-axis and extending past a y-value of 70.

The overall trend showcases how these particular energy levels change, likely in response to varying parameters like ligand field strength. As the x-values increase, the graphs indicate the splitting of the energy levels due to the interactions in a d^3 electron configuration.
