Benchmark Study on the Smallest Bimolecular Nucleophilic Substitution Reaction: H-+CH4 -> CH4+H-
Swart, Marcel; Bickelhaupt, Friedrich Matthias
We report here a benchmark study on the bimolecular nucleophilic substitution (S(N)2) reaction between hydride and methane, for which we have obtained reference energies at the coupled cluster toward full configuration-interaction limit (CC-cf/CBS). Several wavefunction (HF, MP2, coupled cluster) and density functional methods are compared for their reliability regarding these reference data
The following organizations are thanked for financial support: the Ministerio de Ciencia e Innovacion (MICINN, project number CTQ2011-25086/BQU), the DIUE of the Generalitat de Catalunya (project number 2009SGR528, and Xarxa de Referencia en Qu mica Terica i Computacional), the National Research School Combination-Catalysis (NRSC-C), and the Netherlands Organization for Scientific Research (NWO-CW). Financial support from MICINN (Ministry of Science and Innovation, Spain) and the FEDER fund (European Fund for Regional Development) was provided by grant UNGI08-4E-003
