X光电子能谱(ESCA)是研究络合物结构的重要物理方法。根据参与配位的原子在络合前后电子结合能(E_b)的变化,可判断络合物中是否形成配价键以及确定参与配位原子的性质(给予体或接受体)。此外,配位体分子中取代基性质对配位原子电荷密度的影响,在E_b值
X-ray photoelectron spectroscopy (ESCA) is an important physical method to study the complex structure. According to the change of the electron-binding energy (E_b) before and after the complexation of the atoms, the formation of the valence bond in the complex can be judged and the nature of the ligand (donor or acceptor) participating in the coordination can be determined. In addition, the effect of substituent properties on the charge density of the coordination atoms in the ligand molecule shows that at the E_b value
