Calculations of the exited states of ionic forms of xanthene and oxazine dyes are carried out in the π-electron approximation. Electron transition energies, their polarization and electron density redistribution in the exited states are evaluated. The use of charge transfer numbers allowed us to establish a genetic bond of exited singlet states of xantene and oxazine compounds. Quantitative characteristics of the donor activity of substituents (amine- and oxy-groups) are obtained and their contribution to the formation of excited terms is determined with the use of localization numbers.
