Similar to 5 both the G 0 W 0 -and BSE@evGW results show a better alignment with the experiment than TDDFT. Most notably the location of the lowest absorption peak can be reasonably obtained using BSE@GW. Further, a single GW iteration appears to be sufficient to obtain results that are close to the self-consistent ones if the LC-BLYP functional was used. The application of the TDA results in a shift of the spectrum towards higher energies.
