通过基于波函数的电子结构计算,我们确定了准一维自旋链和梯形铜氧化物中的 Cu d-d 激发能。已计算了具有共享角(Sr2CuO3 和 SrCuO2)和共享边缘(LiVCuO4、CuGeO3、LiCu2O2 和 Li2CuO2)CuO4 板、具有共享角 CuF6 八面体 (KCuF3) 的铜酸盐、梯形系统 CaCu2O3 和多铁氧化铜 CuO 的一整套局部激发。我们的数据与 KCuF3 光学吸收测量的现有结果以及 CuO 共振非弹性 X 射线散射实验发现的激发能很好地进行了比较。我们报告的其他材料的从头算结果应该有助于解释未来对这些高度各向异性化合物的共振非弹性 X 射线散射实验。
With wavefunction-based electronic-structure calculations we determine the Cu d-d excitation energies in quasi-one-dimensional spin-chain and ladder copper oxides. A complete set of local excitations has been calculated for cuprates with corner-sharing (Sr2CuO3 and SrCuO2) and edge-sharing (LiVCuO4, CuGeO3, LiCu2O2 and Li2CuO2) CuO4 plaquettes, with corner-sharing CuF6 octahedra (KCuF3), for the ladder system CaCu2O3, and for multiferroic cupric oxide CuO. Our data compare well with available results of optical absorption measurements on KCuF3 and the excitation energies found by resonant inelastic x-ray scattering experiments for CuO. The ab initio results we report for the other materials should be helpful for the interpretation of future resonant inelastic x-ray scattering experiments on those highly anisotropic compounds.
