The absorption and fluorescence spectra of 2-[4-(dimethylamino)phenyl]-3-hydroxy-4H-chromene-4-one in benzene or toluene and in the presence of methanol (proton donor) or the highly polar dimethylsulfoxide (proton acceptor) were measured and analyzed from the point of view of the potential influence
