At high FcN concentration static quenching via an intermolecular electron transfer mechanism constitutes the predominating decay channel for 1MB+*. The time constants of the large amplitude components for the forward electron transfer from FcN donor to 1MB+* and the subsequent recombination process recovering the ground states have been determined to be 390 fs and 1 ps, respectively. Thus, the majority of radical pairs has recombined before paramagnetic relaxation induces spin mixing giving rise to triplet-phased radical pairs. These can escape geminate recombination as the system does not offer low-lying local triplet states to be occupied in the recombination process.</dcterms:abstract> <dc:contributor>Gilch, Peter</dc:contributor> <dc:creator>Michel-Beyerle, Maria Elisabeth</dc:creator> <dc:contributor>Pöllinger-Dammer, Florian</dc:contributor> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:13:30Z</dc:date> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:13:30Z</dcterms:available> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9659"/> <dcterms:issued>1997</dcterms:issued> </rdf:Description> </rdf:RDF>
