Abstract: | Polarographic reduction potentials of seven 3-substituted phenanthrenequinones have been determined in aqueous dioxan and aqueous ethanol under different pH conditions. The substituent effects on the reduction potentials could be correlated with the Hammett σ- constants (correlation coefficients > 0·995). The possibility of using reduction potentials as an accurate measure of resonance energy has been pointed out. |
