Abstract

By providing a customized empirical correction to density functional theory DFT the recently developed DFTsupplemental potential SP approach can provide a postHartree–Fock quality potential energy surface at the cost of DFT The performance of DFTSP is validated by calculating binding energies of small methanewater clusters The method is used to rank several CH4·H2O20 minima previously identified by Hartke The more accurate DFTSP approach identifies methane on edgesharing pentagonal prisms as the lowest energy configuration The methanecentereddodecahedron cage is less stable than the lowest minimum studied in this work by 62 kcal/molThe authors thank Dr Hartke for providing the methanewater structures for our study YS wants to thank Dr Eric Pinnick for helpful discussions The research was funded by the National Science Foundation under CAREER award CHE0748628 The computer resource for this study was provided by the National Center for Supercomputing Applications under Grant No TGCHE070074N and by the Boston University’s Center for Scientific Computing and Visualization
