Here in this work, we simulated a static XE spectrum of SF 6 with a protocol based on DFT-ROCIS RIXS module in ORCA, previously applied to a series of alkenes . The details of this protocol have already been discussed in detail in the Methods section II and in Ingle et al. . In comparison to the Kohn-Sham orbital approximation presented in Fig. (τ = 0.0f s spectrum) in Ekholm et al. , the present protocol results in a static XE spectrum in a better agreement with the experimental spectrum in terms of the peaks intensities and transition energies. Even though in this work we neglect the dynamical effects that were earlier demonstrated to be important , the spectrum simulated with the above mentioned protocol provides an fairly accurate estimation of the experimental XE spectrum.
