UVA-visible photo-excitation of guanine radical cations produces sugar radicals in DNA and model structures

This work presents evidence that photo-excitation of guanine radical cations results in high yields of deoxyribose sugar radicals in DNA, guanine deoxyribonucleosides and deoxyribonucleotides. In dsDNA at low temperatures, formation of C1′• is observed from photo-excitation of G•(+) in the 310–480 n...
