Question
The text and graph provide information about the UV-visible spectrum of [Cr(en)₃]Cl₃. 

### Text:
- **d.** In the UV-visible spectrum for [Cr(en)₃]Cl₃, two peaks at 350 nm and 457 nm are observed. The transition to which excited state gives rise to the peak at 457 nm?
- **e.** In the UV-visible spectrum for [Cr(en)₃]Cl₃, two peaks at 350 nm and 457 nm are observed. The transition to which excited state gives rise to the peak at 350 nm?

### Graph Description:
The graph is a Tanabe-Sugano diagram, which is used to determine the energy levels of d-d transitions in coordination complexes. 

- **Axes:**
  - The x-axis is labeled Δ/B, where Δ represents the crystal field splitting parameter, and B is the Racah parameter.
  - The y-axis is labeled E/B, where E is the energy.

- **Curves:**
  - Various curves are labeled with terms corresponding to electronic states: 
    - \( ^2D \), \( ^4T_1 \), \( ^2A_2 \), \( ^2A_1 \), \( ^4T_2 \), \( ^2T_2 \), \( ^2T_1 \), \( ^2E \), \( ^4A_2 \).
  - The curves represent different electronic transitions possible within the complex as the crystal field strength changes.

This diagram helps identify which electronic transitions correspond to the observed peaks in the UV-visible spectrum of the complex.
