摘要

X-ray absorption spectra of gas-phase VOCl_3and CrO_2Cl_2have been measured in the metal L_(2,3)-edge and CK-edge regions. The assignment of the spectral features is based on the relativistic two-component ZORATDDFT approach. The calculations provide results in excellent agreement with the experimental spectra andprove the importance of including both configuration mixing and spin—orbit coupling in the theoreticadescription to obtain a reliable simulation of the transition metal L_(2,3)-edge. The calculations are extendedalso to the MnO_3Cl molecule to discuss the spectral variations along series of oxychlorides both inthe metal L_(2,3
