A Novel Radical-Triplet Pair Mechanism for Cidep of Free Radicals

The Journal of Physical Chemistry A, 1990
Transient radicals and triplet-state molecules are generated simultaneously in solution by laser irradiation, and chemically induced electron polarization (CIDEP) of the radicals is studied by time-resolved ESR spectroscopy. The triplet-state molecules are found to induce emissive electron spin polarizations due to triplet-state quenching by radicals ...

The Thermal Sulfenate−Sulfoxide Rearrangement:  A Radical Pair Mechanism

Journal of the American Chemical Society, 2000
The thermal reaction of sulfenates (RS−OR), yielding their corresponding sulfoxides (RS(O)R), was studied experimentally. The first step of the reaction was found to be the formation a radical pair by homolytic cleavage of the carbon−oxygen bond of the sulfenate.

Resonance effects indicate a radical-pair mechanism for avian magnetic compass

Nature, 2004
Migratory birds are known to use the geomagnetic field as a source of compass information. There are two competing hypotheses for the primary process underlying the avian magnetic compass, one involving magnetite, the other a magnetically sensitive chemical reaction.

Damage mechanism of hydroxyl radicals toward adenine—thymine base pair

Chinese Physics B, 2014
The adenine-thymine base pair was studied in the presence of hydroxyl radicals in order to probe the hydrogen bond effect. The results show that the hydrogen bonds have little effect on the hydroxylation and dehydrogenation happened at the sites, which are not involved in a hydrogen bond, while at the sites involved in hydrogen bond formation in the ...

Quartet Pair and Radical Quartet Pair Mechanisms of Electron Spin Polarization Developed within Nonbonded Dimers

Applied Magnetic Resonance, 2009
Novel mechanisms of the electron spin polarization were reported. Effect of spin-selective interactions within the photo-excited preexisting molecular dimers was utilized. Processes occurring within dimers and upon escape from the dimer cage were considered.

Role of chiral-induced spin selectivity in the radical pair mechanism of avian magnetoreception

Physical Review E, 2022
In this paper, we investigate the effect of chiral-induced spin selectivity (CISS) on the radical pair mechanism of avian magnetoreception. We examine the impact of spin selectivity on the avian compass sensitivity. In this analysis, we also consider the dipolar and exchange interactions and observe their interplay with CISS.
