In contrast, electron-transfer quenching of quinone triplets leads to triplet radical-ion pairs which are long-lived owing to the spin restriction in the back-electron-transfer deactivation (see: Jones, G., II.

61. The conformational structure of hexaethylbenzene with the methyl groups projecting alternately above and below the ring plane (see: Iverson, D. J.; Hunter, G.; Blount, J. F.; Damewood, J. R., Jr.; Mislow, K. J. Am. Chem. Soc. 1981, 103, 6073) precludes the close approach of a quinone π-acceptor, as required in the formation of intermolecular EDA complexes. The full implications of such steric hindrance on CT complex formation will be reported in a forthcoming paper (Rathore, R. Unpublished results).

99. 2 (π, π*) state also have zero dipole moments. The conclusion that the structures and dipole moments of the singlet and triplet states of quinones are similar is furthermore supported by the similarity of their absorption spectra (see Figures 1, 7, and 9). Thus, for most quinones, the absorption maxima and extinction coefficients in the singlet and triplet spectra are about the same. The principal difference is that the absorption bands of the triplet states show a fine structure, whereas those of the singlet states exhibit a more or less (smooth) Gaussian shape.
