Figure shows experimental XES spectra of H 2 S 110 and CH 3 Cl 111 at the sulfur and chlorine K-edges, juxtaposed with simulated CAM-B3LYP/CIS spectra. (The calculations use the procedure that was outlined in Section II D, based on the maximum overlap method. ) The simulated spectra are in reasonable agreement with experiment and require smaller shifts as compared to other TD-DFT approaches. This means that the accuracy is much improved relative to TD-B3LYP or TD-CAM-B3LYP, which we attribute to the additional Hartree-Fock exchange that is incorporated either at short range (in the case of the SRC1 functionals, which were used to parameterize ∆ε) or else added directly to the CIS matrix elements (for CAM-B3LYP/CIS). However, the shift that is needed to match experiment is about 28 eV for CH 3 Cl, which is larger than what was required for chlorine K-edge absorption in CH 3 Cl (see Table ), and also larger than the shifts required to match experiment for (cyclopentadienyl)titanium compounds (Section IV E).
