利用自旋配对密度函数理论,采用具有高度可转移性的a-Kohn-Sham修正方案,可以有效地计算分子和体材料中核心电子的绝对结合能。这些偏移取决于核心水平和原子种类,可以通过比较能量实验分子x射线光电子能谱。我们证明了正确的预测的绝对和相对结合能在广泛的分子,金属和绝缘体。
Absolute binding energies of core electrons in molecules and bulk materials can be efficiently calculated by spin paired density-function theory employing a-Kohn-Shamscheme corrected by offsets that are highly transferable. These offsets depend on core level and atomic species and can be determined by comparingenergies to experimental molecular x-ray photoelectron spectra. We demonstrate the correct prediction of absolute and relative binding energies on a wide range of molecules, metals, and insulators.
