【摘要】 <正> 研究X-射线吸收近边结构(X-Ray Absorption Near Edge Structure简称XANES)可以得到配位几何学、吸收原子价态等重要的结构信息。Cramer等人曾经研究过钼化合物的MoK X-射线吸收边的临界能及其影响因素,归纳为以“配位电荷”表示的经验公式。更多还原

【Abstract】 In this article, the variation rule of critical energy of center absorption atom along with the valence of center atom, the type of ligand atom, the coordination number and the distance between nuclei has been summed up from the data of EXAFS spectra Mok absorption edge critical energy of molybdenum compounds, and is expressed by the formula of "shift factor" . This formula is suitable for the simple Mo compounds and for the. complicate Mo compounds including the Mo cluster compounds.更多还原
