3) When the absorption spectra is calculated usually it is ignored the vibronic substructure of electronic levels. In other words the energy of so-called 0->0 transition is calculated, which not always correspond to maxima of first absorption band observed in the experiment. It may happens that the absorption maxima correspond to e.g. 0->1 or even 0->2 transition. If the latter one is true then comparison of calculated and measured spectra is less accurate. Author should check this and mention in the manuscript.
