Abstract

Absorption frequency-dependent polarisation spectra of fluorescence (APF) and dichroism on oriented polyvinyl alcohol sheets have been measured and used as a basis for interpretation of absorption spectra of 1- and 2-amino-9,10-anthraquinones in the region 250-600 nm. Character of the excited states was determined by the method of configuration analysis (PPP-CA).
