Advancements in synchrotron and tabletop light sources have made the study of core-level photochemistry in the x-ray regime more accessible, providing unprecedented insights into the interplay of electronic and nuclear structure. While experimental technology bounds ahead, common computational methods such as time-dependent density functional theory (TDDFT) face significant challenges, particularly with x-ray absorption spectra (XAS), where errors can exceed 10 eV. Such substantial errors… Read More
