## Abstract The ESR. spectra of the radical anions of three cyclazines are described. Their Οβspin distributions are discussed in terms of simple MO theory and compared with those of structurally related species.

The reaction between a hydroquinone aqueous solution and manganese dioxide has been investigated by electron paramagnetic resonance spectroscopy. A very stable pbenzosemiquinone anion is formed when an aqueous solution of hydroquinone is passed through a column of manganese dioxide. The kinetics for
Resonance Raman spectra of p-benzosemiquinone radical anion excited in the 340-430 nm region are reported. Prominent bands, which are not present in the 430 nm spectrum, arc observed at t472 and 127 I cm-' in the 370 nm spectrum. These bands arc attributed to the non-totally symmetric (b,,) modes, v
