The respective DFT and TDDFT calculations have been done with Gaussian 6 and QChem 7 program suites. The assignment of excited states was done based on the analysis of the density-matrix. For the spectra, a phenomenological broadening by a Gaussian line shape (FWHM = 0.2 eV) was employed. Solvent effects (acetonitrile) for DFT/TDDFT calculations were included within the polarized continuum model (PCM) approach. Note that the tuning of range-separation parameters was done in vacuum as it was shown previously that tuning combined with the PCM model leads to the underestimation of the exact exchange percentage in the constructed functional.
