From the experimental results the absolute values of the rate parameters characterizing the primary radical ion pair (kce for cage escape, τs for spin relaxation, and kbet for spin-allowed backward electron transfer) have been obtained. Particularly noteworthy is the strong viscosity dependence of kbet , which can be assigned to dielectric solvent relaxation as the rate limiting step of backward electron transfer in the EGLY containing solvents.</dcterms:abstract> <dc:language>eng</dc:language> <dc:format>application/pdf</dc:format> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:14:52Z</dc:date> <dc:creator>Bürßner, Dieter</dc:creator> <dc:creator>Wolff, Hans-Joachim</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9852"/> <dcterms:title>Spin-orbit coupling controlled spin chemistry of Ru(bpy)3 2+ photooxidation : detection of strong viscosity dependence of in-cage backward electron transfer rate</dcterms:title> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:14:52Z</dcterms:available> <dcterms:issued>1995</dcterms:issued> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:contributor>Wolff, Hans-Joachim</dc:contributor> <dc:creator>Steiner, Ulrich</dc:creator> <dc:contributor>Bürßner, Dieter</dc:contributor> <dc:rights>deposit-license</dc:rights> <dcterms:bibliographicCitation>First publ. in: Pure and applied chemistry 67 (1995), 1, pp. 167-174</dcterms:bibliographicCitation> <dc:contributor>Steiner, Ulrich</dc:contributor> </rdf:Description> </rdf:RDF>
