On the mechanism of multiplet CIDEP in radical ion pairs
Chemical Physics Letters, 1997It is shown that multiplet chemically induced dynamic electron polarization (CIDEP) in radical ion pairs is unlikely to be caused by electron spin exchange (J>0), unless the rate of electron transfer is slowed down either by exciplex formation or by a low Franck-Condon factor.

Mechanism of primary and secondary ion-radical pair formation in photosystem I complexes
Biochemistry (Moscow), 2014The mechanisms of the ultrafast charge separation in reaction centers of photosystem I (PS I) complexes are discussed. A kinetic model of the primary reactions in PS I complexes is presented. The model takes into account previously calculated values of redox potentials of cofactors, reorganization energies of the primary P700(+)A0(-) and secondary P700(

Abstract It is shown that the conventional use of an equation in which the electron spin polarization is dependent simply upon the square root of the magnetic mixing parameter, Q (see text), is inadequate to account for pure radical pair mechanism polarization effects in isopropyl radicals, and by implication most radicals.

Reinvestigation by stopped-flow spectrophotometry of the previously observed influence of a static magnetic field on the horseradish peroxidase (HRP)-catalyzed reduction of hydrogen peroxide by Taraban et al. (J. Am. Chem. Soc. 1997, 119, 5768) did not reproduce the originally observed effects. No magnetic field effect was observed for static fields of

A perturbation theory treatment of oscillating magnetic fields in the radical pair mechanism
Chemical Physics, 1994Abstract This paper describes an application of time-dependent perturbation theory to the calculation of singlet-to-triplet yields in radical pair reactions for oscillating magnetic fields. It outlines an iterative approach, based on the Schrodinger equation, that should hold for any order of perturbation theory and then gives explicit expressions up

The induction of quantum beats by the Δg mechanism in radical ion pair recombination
Chemical Physics Letters, 1987Abstract Quantum beats induced by the difference in g factors between radicals in a pair have been detected in recombination fluorescence kinetics in dilute solutions of diphenyl sulfide and paraterphenyl in cis-decalin following irradiation by fast electrons. Good agreement between theory and experiment is obtained.

Radical Pair Mechanism of Chemically Induced Magnetic Polarization
1977Chemically induced magnetic polarization (CIMP) refers to various processes whereby free radical reactions in liquids lead to nonequilibrium population of the nuclear spin states of the products and reactants, and similar anomalies in the electron spin state population of the free radical intermediates.
