This procedure is free of fragmentation. Upon infrared excitation, size- and isomer-specific OH-stretch spectra are obtained over a large range of cluster sizes. In one application of this method the infrared spectra of single water cluster sizes are investigated. A comparison with calculations, based on structures optimized by genetic algorithms, has been made to tentatively derive cluster structures which reproduce the experimental spectra. We identified a single all-surface structure for n = 25 and mixtures with one or two interior molecules for n = 24 and 32. In another application the sizes are determined at which the crystallization sets in. Surprisingly, this process strongly depends on the cluster temperature. The crystallization starts at sizes below n = 200 at higher temperatures and the onset is shifted to sizes above n = 400 at lower temperatures."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft [ZE 890 1-1, 2, GRK 782]"],["dc.identifier.doi","10.1039/c3cp55185g"],["dc.identifier.fs","609790"],["dc.identifier.isi","000333121300004"],["dc.identifier.pmid","24603719"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10128"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/34864"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Royal Soc Chemistry"],["dc.relation.issn","1463-9084"],["dc.relation.issn","1463-9076"],["dc.rights.access","openAccess"],["dc.title","A size resolved investigation of large water clusters"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The appearance of stable (H2O)(n) cluster isomers having a fully coordinated interior molecule has been theoretically predicted to occur around the n = 20 size range. However, our current knowledge about the size regime in which those structures become energetically more stable has remained hypothetical from simulations in lieu of the absence of precisely size-resolved experimental measurements. Here we report size and isomer selective infrared (IR) spectra of (H2O) 20 clusters tagged with a sodium atom by employing IR excitation-modulated photoionization spectroscopy. The observed absorption patterns in the OH stretching region are consistent with the theoretically predicted spectra of two structurally distinct isomers of exceptional stability: a drop-like cluster with a fully coordinated (interior) water molecule and an edge-sharing pentagonal prism cluster in which all atoms are on the surface. The drop-like structure is the first experimentally detected water cluster exhibiting the local connectivity found in liquid water."],["dc.identifier.doi","10.1039/c4cp03642e"],["dc.identifier.fs","609795"],["dc.identifier.isi","000345453200034"],["dc.identifier.pmid","25231162"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11429"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/34674"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Royal Soc Chemistry"],["dc.relation.issn","1463-9084"],["dc.relation.issn","1463-9076"],["dc.rights.access","openAccess"],["dc.title","Infrared detection of (H2O)(20) isomers of exceptional stability: a drop-like and a face-sharing pentagonal prism cluster"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
