A study of the Mn K absorption pre-edges in oxides using resonant inelastic X-ray scattering (RIXS) spectroscopy is presented. The energy transfer dimension enhances the separation of the pre-edge (predominantly 1s to 3d transitions) from the main K-edge and a detailed analysis is thus possible. The RIXS spectra are sensitive to the Mn spin state. The technique thus yields detailed information on the electronic structure that is not accessible in conventional K-edge absorption spectroscopy. The line splittings can be understood within a ligand field multiplet model, showing the importance of (2p,3d) two-electron interactions that give rise to the spin-sensitivity.

Mn K 吸收前缘的共振非弹性 X 射线散射 (RIXS) 光谱——3d 轨道的直接探测

介绍了使用共振非弹性 X 射线散射 (RIXS) 光谱研究氧化物中的 Mn K 吸收前缘。能量转移维度增强了前边缘（主要是 1s 到 3d 过渡）与主 K 边缘的分离，因此可以进行详细分析。RIXS 光谱对 Mn 自旋态敏感。因此，该技术产生了在传统 K 边吸收光谱中无法获得的关于电子结构的详细信息。可以在配体场多重态模型中理解线分裂，显示了引起自旋敏感性的 (2p,3d) 两电子相互作用的重要性。
