A Fourier transform EPR study of uracil and thymine radical anions in aqueous solution
Literature Information
S. Naumov
Hydrated electrons are generated by two photon ionization of anthraquinone-1,5-disulfonate in H2O and D2O solutions. The electron attachment to the pyrimidine-type bases thymine and uracil results in the thymine and uracil radical anions. By simulation of the EPR splitting patterns of the protonated and deuterated forms of the radical anions their hyperfine coupling constants are assigned unambiguously. This new assignment of all hfs coupling constants is supported by quantum chemical calculations. The kinetics of electron attachment to the pyrimidine-type bases was studied by the method of kinetic linebroadening effects of the hydrated electron. The rate constants of the electron attachment were determined as katt(thymine) = katt(uracil) = (2.7 ± 0.1) × 109 M−1 s−1.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
