The principle of the experimental technique is to irradiate the solution in a flow-through cuvette within a magnetic field which is varied in steps and to observe optical density changes in a second cuvette connected to the first one in a flow system. Although the absolute quantum yields of the two photoreactions are below 1%, relative changes due to the magnetic field effect could be resolved with an accuracy of 1%. The observed effects on the permanent photo bleaching yield closely follow the effects on the radical yield previously observed in time-resolved experiments and are explained by the radical pair mechanism and the triplet mechanism, respectively.</dcterms:abstract> <dcterms:issued>1985</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:14:47Z</dc:date> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
