论文摘要
显示了通过涉及X射线吸收在TC L3边缘附近X射线吸收（XANES）的新方法测定TC氧化态的一般策略。在晶体场多重组理论的框架内测量并随后模拟了从氧化状态I到VII的全面的99TC化合物。吸收边缘能量转移的可观察趋势与光谱形状相结合，可以更深入地了解复杂的TC配位化学。这种方法可以扩展到TC系统的大量研究，因为该方法是准确的TC氧化态和配体表征的最敏感方法之一。
A general strategy for the determination of Tc oxidation state by new approach involving X-ray absorption near edge spectroscopy (XANES) at the Tc L3 edge is shown. A comprehensive series of 99Tc compounds, ranging from oxidation states I to VII, was measured and subsequently simulated within the framework of crystal-field multiplet theory. The observable trends in the absorption edge energy shift in combination with the spectral shape allow for a deeper understanding of complicated Tc coordination chemistry. This approach can be extended to numerous studies of Tc systems as this method is one of the most sensitive methods for accurate Tc oxidation state and ligand characterization.
