Organic free radicals are ubiquitous in chemical and biological systems. They are involved
in a huge number of fundamental processes going from simple organic reactions1-3 through …

Density-functional theory (B3LYP functional) is used to investigate the ionization potentials
and electron affinities of the DNA and RNA nucleotide bases. For the first time, anions lying …

The effects of oligonucleotide sequence, base pairing, stacking, and duplex microstructure
as well as donor–acceptor distance, labeling site, and driving force on charge‐transfer …

The induction of base damage products in γ-irradiated DNA, hydrated between 2.5 and 32.8
moles of water per mole of nucleotide (Γ), was investigated using the gas …

An overview of the early processes initiated in DNA by ionizing radiation is given from the
perspective of studies done by solid-state EPR with the focus on radical combination …

The geometries, spin density distributions, and hyperfine coupling constants (HFCC) in
possible radiation products of guanine are studied through the use of density functional …

It has long been assumed that the population of radicals trapped in irradiated DNA (that is,
the radicals escaping recombination) would quantitatively account for the lesions observed …

Understanding the basic chemistry of the interaction of radicals with DNA bases is
imperative when trying to elucidate the potential effects of radiation on DNA. Experimental …

The killing of tumor cells by ionizing radiation beams in cancer radiotherapy is currently
based on a rather empirical understanding of the basic mechanisms and effectiveness of …

The yields of radicals trapped on DNA, measured by EPR spectroscopy of
oligodeoxyribonucleotide crystals (the EPR spectrum of a single crystal of d (CCCTAGGG) is …
