It is demonstrated for the case of photo-excited ferrocyanide how time-resolved soft X-ray absorption spectroscopy in transmission geometry at the ligand K-edge and metal L₃-edge provides quantitatively equivalent valence electronic structure information, where signatures of photo-oxidation are assessed locally at the metal as well as the ligand. This allows for a direct and independent quantification of the number of photo-oxidized molecules at two soft X-ray absorption edges highlighting the sensitivity of X-ray absorption spectroscopy to the valence orbital occupation of 3d transition metal complexes throughout the soft X-ray range.

从金属和配体的角度定量评估3d过渡金属配合物中的瞬态价轨道占据

对于光激发的亚铁氰化物，证明了在配位体K边缘和金属L ₃边缘的透射几何中时间分辨的软X射线吸收光谱法如何提供定量等效的价电子结构信息，其中光氧化的签名在金属以及配体上均进行局部评估。这允许直接和独立地量化两个软X射线吸收边缘处的光氧化分子的数量，从而突出显示X射线吸收光谱对整个软X射线范围内3d过渡金属络合物的价态轨道占据的敏感性。
