ESR spectra of o-semiquinone radicals produced by dnect photolysis of pyrocatechol in various solvents are reported. In aprotic. neutral solvents the kinetic effects in the ESR spectra reflect the dynamics of the intramolecular hydrosen hond, %hich is superimposed by intermolecular processes in the
ESR study of the effect of water on the kinetics of proton transfer and exchange in solutions of semiquinone radicals
