DFT-ROCIS and with TD-DFT, for the |F1s -1 6a 1 1g resonance, yield RIXS spectra with all essential features and correct polarization dependence. The polarization dependence generally and particular as we see here for a highly symmetrical molecule, like SF 6 provides insights into the local symmetry of various orbitals and also for particular cases provides information on the localiza-tion of the orbital on a particular atom. Here we can say beyond the gerade and ungerade symmetry of the states/orbitals, the polarization dependence really characterizes the σ and π symmetry of various MOs with respect to the S-F bond axis aligned to the incident radiation. For example in the |F1s -1 6t 1 1g resonance, the 6a 1g orbital which always has a σ symmetry with respect to the S-F bond axis, along with the 3e g and 4t 1u orbitals which also have σ symmetry are vertically polarized. This also reflected in the case of the |F1s -1 2t 1 2g resonance, where 2t 2g orbitals having π symmetry with respect to the S-F bonds and similarly orbitals having σ symmetry, i.e. 3e g and 4t 1u and one of the triply degenerate 1t 2u has emission with horizontal polarization. As seen also in the case of the |F1s -1 6t 1 1u resonances, TD-DFT/CAM-B3LYP fails to predict the correct polarization dependence, yet predicting correct energy loss of the peaks in the RIXS spectrum. We find that TD-DFT/CAM-B3LYP follows the same trend for the |F1s -1 2t 1 2g resonance, see FIG. . We clearly see that DFT-ROCIS predicts a correct polarization dependence, with respect to intensities, for the most intense peak corresponding to the |1t -1 2u 2t 1 2g and |5t -1 1u 2t 1 2g states.
