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 ...

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.

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.

On the mechanism of antiphase electron spin resonance spectra of radical pairs

The Journal of Chemical Physics, 1998
We have investigated the origin of the antiphase structure of the mw-induced ESR spectrum of a radical pair in a micelle. By applying an accurate numerical method we have examined various specially designed cases that clearly distinguish between the proposed mechanisms for the production of antiphase structure.
