This is marked by a vertical dashed line labeled **$E_{t_{2g}}$**. * **Peak 2 ($E_{e_g}$):** Reaches a secondary maximum of ~18 units at $E_i \approx 576.3$ eV. This is marked by a vertical dashed line labeled **$E_{e_g}$**. * **Tail:** Intensity decays to ~5 units by $E_i = 580.5$ eV. * **Series D1 (Orange Circles):** * **Trend:** Significantly lower intensity than D2. Shows a multi-peak structure that mirrors the resonance positions of D2 but with different relative weights. * **Feature 1:** Small peak of ~4.5 units at $E_i \approx 575.5$ eV. * **Feature 2:** Peak of ~5.2 units at $E_i \approx 576.4$ eV (near the $E_{e_g}$ resonance). * **Baseline:** Remains between 1 and 4 units across the rest of the range. --- ## 4.
