利用共振非弹性X射线散射（RIXS）谱研究了氧化物中Mn K吸收前边缘。能量转移维度增强了前边缘（主要是1s到3d的过渡）与主K边缘的分离，因此可以进行详细的分析。RIXS光谱对Mn的自旋态很敏感。因此，该技术产生的电子结构的详细信息，这是无法在传统的K边吸收光谱。线分裂可以理解内的配位场多重态模型，显示的重要性（2p，3d）两个电子的相互作用，引起自旋灵敏度。
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.
