โฆ Synopsis
Low-field (L band) chemically induced dynamic electron polarization (CIDEP) in radical pair recombination in liquids is theoretically investigated. Simple analytical expressions for the low-field ST o and ST+ contributions are derived. It is shown that the characteristic features of the low-field ST+ mechanism of CIDEP qualitatively differ from those predicted by the conventional ST_ mechanism.
