| 摘 要： | The weak pre-edge features in the Mn AT-edge X-ray absorption near-edge structure (XANES) spectrum of manganese monoxide (MnO) were investigated by comparing experimental data with dipolar and quadrupolar cross-section calculations in the framework of multiple-scattering theory. We assign the first pre-edge feature to a direct quadrupolar transition from Is core state to 3d molecular orbitals of the central atom, e.g., the lowest in energy, due to the more effective attraction of the core hole. The second peak in this region arises unambiguously from the hybridization between p-orbitals of the central atom with higher-shell metal octahedral orbitals.
