The replacement of one bpy by two cyanide ligands results in an increase of the quenching rate constant and a decrease of the cage escape efficiency. The latter is decreased in a magnetic field and the sensitivity of this effect is weakened by introducing CN- ligands. From the analysis of the magnetic field dependence it can be inferred that with increasing number of CN- ligands, backward electron transfer rate and spin relaxation time in the geminate radical pair exhibit a moderate decrease but that the rate constant of cage escape decreases very strongly.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: Inorganica chimica acta 338 (2002), pp. 133-141</dcterms:bibliographicCitation> <dc:creator>Horváth, Attila</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:12:40Z</dcterms:available> <dc:contributor>Steiner, Ulrich</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9549"/> <dc:rights>deposit-license</dc:rights> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:creator>Fodor, Lajos</dc:creator> <dcterms:title>Ligand dependence of magnetic spin effects on photooxidation of [Ru(bpy)3-n(CN)2n](+2-2n) type complexes</dcterms:title> <dc:contributor>Horváth, Attila</dc:contributor> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
