One-electron reduction of o,o‘-diphenylenebromonium (DPB) and o,o‘-diphenyleneiodonium (DPI) cations in low-temperature glasses produces free radical intermediates whose halogen hyperfine couplings suggest significant spin densities on bromine (0

ESR spectroscopy at low temperatures is employed to investigate electron transfer within DNA doped with randomly spaced electron traps. The traps were introduced by careful bromination of DNA in ice-cooled aqueous solution. The procedure is shown by

Bisulfite anions and sulfinic acids are shown by ESR spectroscopy to undergo reduction with radiolytically produced free electrons and oxidation by hole centers (Cl2•-) in a low-temperature aqueous LiCl glass. Electron-reduced intermediates display

This work presents experimental evidence that the unusual properties of the thiyl peroxyl radical result from specific nucleophilic solvation of sulfur, which stablizes the charge transfer state, RS{sup +}OO{sup *-}. We find that theoretical MO calcu

Several electron scavengers that irreversibly form potential hydrogen-abstracting species upon one-electron reduction have been tested as agents for conversion of reductive damage to DNA bases into damage to the sugar-phosphate backbone. Electron spi

The free radicals produced from the irradiation of hydrated DNA with a heavy-ion beam have been investigated by ESR spectroscopy. The dominant free radical species formed after 60 MeV/nucleon (16)O(8+) ion-beam irradiations at low temperatures (77 K)

An investigation of electron transfer in DNA at low temperatures in an aqueous glassy medium is reported for a system in which electrons are generated by radiation and trapped on DNA. The transfer ...
