On the basis of measurement of absorption frequency-dependent polarisation spectra of fluorescence (APF) and dichroism on oriented polyvinyl alcohol sheets interpretation has been carried out of absorption spectra of α,α'-diamino-9,10-anthraquinones in the wavelength range 250 to 600 nm. Character of the excited states has been determined by the method of configuration analysis (PPP-CA).
