Optical spectra of the hydrogenated naphthalene cation Hn-C10H8^+ for n=1,2, and 10, as well as of the astrobiologically interesting hydrogenated proflavine cation Hn-C13H11N3^+ for n=1 and 14, are calculated. The pseudopotential time dependent density functional theory is used. It is found that the fully hydrogenated proflavine cation H14-C13H11N3^+ shows a broad spectrum where positions of individual lines are almost lost.
