TL;DR: Comparison of the shape of spectra obtained in the case of cytosine, thymine, 2-deoxy- d -ribose and related nucleotides suggests that in these nucleotide, the free radical induced by a biphotonic mechanism is localised in the base whereas the photodynamic component ROO· would be associated with the pentose moiety of nucleotide.

Free Radical Formation in Deoxyguanosine-5′-Monophosphate γ-Irradiated in Frozen Solution. A Computer-Assisted Analysis of Temperature-Dependent ESR Spectra
TL;DR: Deoxyguanosine-5′-monophosphate was γ-irradiated at 77 K in frozen aqueous solution and then annealed in a stepwise fashion up to the melting point and found to be quite similar to that of dAMP.

TL;DR: UV irradiation of nucleic acids and related model compounds produces electronically excited bases that are able to undergo various photochemical reactions involving neighboring bases, sugar residues, surrounding water molecules, proteins, and bound organic ligands.

Sensitized photooxygenation reactions and the role of singlet oxygen.
David R. Kearns,Ahsan U. Khan +1 more
TL;DR: The results presented in this paper strongly support the suggestion that many of the observed photodynamic effects could be due to reactions of singlet oxygen.

Double integration of electron spin resonance spectra
TL;DR: In this article, a method for obtaining the double integration of electron spin resonance spectra, with the aid of a desk calculating machine, was described. But the method automatically corrects for base-line drift.

TL;DR: It is shown that electron reactions can account for the formation of the eight-lined E.R.S. spectrum formed in the radiolysis of thymine-containing compounds including DNA.

Photoionisation and biphotonic processes of nucleic acids derivatives in frozen solutions
TL;DR: In this paper, a biphotonic absorption process involving the lowest triplet state is suggested, which leads to a decrease of the phosphorescent triplet-state population of the molecules tested.
