Lifetimes and Reaction Pathways of Guanine Radical Cations and Neutral Guanine Radicals in an Oligonucleotide in Aqueous Solutions

The exposure of guanine in the oligonucleotide 5’-d(TCGCT) to one-electron oxidants leads initially to the formation of the guanine radical cation G(•+), its deptotonation product G(−H)(•) and, ultimately, to various two- and four-electron oxidation products via pathways that depend on the oxidants...
