Magnetic Field Effects on Reaction Yields in the Solid-State:An Example from Photosynthetic Reaction Centers
Magnetic Field Reaction Yields in the Solid-State Photosynthetic Reaction Centers
2016/5/20
Prior to 1970there were several reports of the effects of magneticfields on chemical reactions, though there was muchrebuttal and retraction in this early literature (1-3). Since 1970, the number of r...

Dependence of the Yield of a Radical-Pair Reaction in the Solid State on Orientation in a Magnetic Field
Radical-Pair Reaction Solid State on Orientation Magnetic Field
2016/5/20
We report the observation that the yield of a radical-pair reaction in the solid state can depend strongly on the orientation of the reactants in a magnetic field. This phenomenon is expected to be qu...
