Those clusters with an odd number of atoms tend to react much more slowly than their even-numbered counterparts. We used Fourier transform ion cyclotron resonance mass spectrometry to show that spin conservation straightforwardly accounts for this trend. The reaction rate of odd-numbered clusters increased appreciably when singlet oxygen was used in place of ground-state (triplet) oxygen. Conversely, monohydride clusters AlnH-, in which addition of the hydrogen atom shifts the spin state by converting formerly open-shell structures to closed-shell ones (and vice versa), exhibited an opposing trend: The odd-n hydride clusters reacted more rapidly with triplet oxygen. These findings are supported by theoretical simulations and highlight the general importance of spin selection rules in mediating cluster reactivity.</dcterms:abstract> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-22T17:52:36Z</dcterms:available> <dc:creator>Jena, Purusottam</dc:creator> <dc:creator>Grubisic, Andrej</dc:creator> <dc:creator>Stokes, Sarah T.</dc:creator> <dcterms:bibliographicCitation>First publ. in: Science 319 (2009), 5862, pp. 438-442</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/977"/> <dc:contributor>Stokes, Sarah T.</dc:contributor> <dc:creator>Bowen, Kit H.</dc:creator> <dc:contributor>Ganteför, Gerd</dc:contributor> <dc:language>eng</dc:language> <dcterms:issued>2008</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-22T17:52:36Z</dc:date> <dc:contributor>Bowen, Kit H.</dc:contributor> <dc:contributor>Schnöckel, Hansgeorg</dc:contributor> <dc:contributor>Grubisic, Andrej</dc:contributor> <dc:creator>Ganteför, Gerd</dc:creator> <dc:contributor>Kiran, Boggavarapu</dc:contributor> <dc:contributor>Li, Xiang</dc:contributor> <dc:creator>Kiran, Boggavarapu</dc:creator> <dc:creator>Li, Xiang</dc:creator> <dc:contributor>Jena, Purusottam</dc:contributor> </rdf:Description> </rdf:RDF>
