Wide-Band, Time-Resolved Photoacoustic Study of Electron-Transfer Reactions: Photoexcited Magnesium Porphyrin and Quinones

Wide-band, time-resolved, pulsed photoacoustics has been employed to study the electron-transfer reaction between a triplet magnesium porphyrin and various quinones in polar and nonpolar solvents.The reaction rate constants are near encounter limited.The yield of triplet state is 70percent in both solvents.The yield of ions is 85percent in the former and zero in the latter, in agreement with spin dephasing time and escape times from the Coulomb wells in the two solvents.In methanol the plot of measured heat output versus quinone redox potential is linear.This implies that the entropy of electron transfer is constant through the series, but it may not be negligible.

The Electron Spin Resonance Spectra of Semiquinones obtained from Some Naturally Occurring Methoxybenzoquinones

Radical anions of methoxyquinones and related compounds were generated in a static system in alkaline media.The unpaired electron distribution in these radicals could not be satisfactorily verified by simplified SCF calculations.It is shown that a simple relationship exists between splittings in semiquinones and corresponding splittings in the closely related alkyl aryl ether radical cations.The relationship correlates very closely with the exsess charge effect which has been examined quantitatively for aromatic hydrocarbon radical ions, indicating that the same effect is operative in the oxygenated radicals, in which the splittings of the cations are ca. 20percent greater than corresponding splittings in the anions.These correlations, together with observed smooth variations of splitting patterns with substitution have permitted unambiguous assignment of the coupling constants of radicals such as the fumigatin anion or the 1,2-methylenedioxynaphthalene cation, without recourse to new computation.
