用软X射线荧光测量研究了LiBC的电子结构。共振非弹性X射线散射（RIXS）光谱测量与激发能量调谐到硼和碳的K-边缘。RIXS光谱显示色散的功能，这是分配给计算的能带使用站点选择性定量带映射方法的基础上的概念，k-动量守恒。它的结论是，虽然电子结构的计算是在一般协议与实验光谱，碳和硼的K-发射带显示出一定的偏差，由于C2 p-B 2 p状态的不完全杂化。
The electronic structure of LiBC has been studied using soft x-ray fluorescence measurements. Resonant inelastic x-ray scattering (RIXS) spectra were measured with the excitation energy tuned to the boron and carbon K-edges. RIXS spectra show dispersive features, which were assigned to the calculated energy bands using the site-selective quantitative band mapping method based on the concept of k-momentum conservation. It is concluded that while the electronic structure calculations are in general agreement with experimental spectra, carbon and boron K-emission bands show some deviation due to an incomplete hybridization of the C 2p–B 2p states.
