The one-photon UV/Vis absorption spectra presented below were obtained from PE-TDDFT calculation using the fully long-range corrected CAM-B3LYP functional and the 6-31+G* basis set. All PE-TDDFT calculations were performed in the Dalton program. In all the presented spectra, the lowest lying 12 transition energies and oscillator strengths for all systems were used to compute absorption spectra broadened with Gaussian line shapes with a broadening factor of 0.2 eV.
