Tautomerism of anthraquinones: III. Tautomerization and rotational isomerization as processes responsible for the appearance of several π1,π*-bands in the absorption spectra of hydroxy-substituted quinones*bands in their electronic absorption spectra. Each π1,π*band can be assigned to a particular tautomer and conformer
