After testing and validation by comparison with existing methods, the algorithm is applied to investigate the effect of cut-off truncation and artificial periodicity in explicit-solvent simulations of ionic solvation and ion–ion interactions. Both cut-off truncation and artificial periodicity significantly alter the polarization around a spherical ion and thus, its solvation free energy. The nature and magnitude of the two perturbations are analyzed in details, and correction terms are proposed for both effects. Cut-off truncation is also shown to induce strong alterations in the potential of mean force for ion–ion interaction. These observations help to rationalize artifacts previously observed in explicit–solvent simulations, namely spurious features in the radial distribution functions close to the cut-off distance and alterations in the relative stabilities of contact, solvent-separated and free ion pairs.</dcterms:abstract> <dc:creator>Bergdorf, Michael</dc:creator> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/29"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-10-05T07:59:11Z</dcterms:available> <dcterms:issued>2003-11</dcterms:issued> <dc:creator>Peter, Christine</dc:creator> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/40243"/> <dc:contributor>Hünenberger, Philippe H.</dc:contributor> <dc:language>eng</dc:language> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Bergdorf, Michael</dc:contributor> <dc:creator>Hünenberger, Philippe H.</dc:creator> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/29"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-10-05T07:59:11Z</dc:date> </rdf:Description> </rdf:RDF>
