Eriksson et al. (2011) investigated the ability of LC hybrid functionals ωB97, ωB97X and ωB97X-D within the TD-DFT framework. They found that ωB97X reproduces the experiment best with an error of up to 0.09 eV. Additionally, it was confirmed that the applied functional for geometry optimization has only a small influence on the calculated spectra. Lee et al. (2012) benchmarked five DFT functionals (B3LYP, LC-ωPBE, LC-BLYP, CAM-B3LYP and ωB97X-D) using TD-DFT for PP derivative. It was found that ωB97X-D yields the best agreement to the reference for the LC functionals (Qave bands: 0.055 eV). Overall, better results were obtained for B3LYP for the Soret and Q-bands. However, it was not recommended due to the susceptibility for charge transfer excitations.
