  1. Dimetallic sulfide endohedral metallofullerene Sc2 S@C76 : Density functional theory characterization.

    Journal Of Computational Chemistry 35(22):1657 (2014) PMID 24962983

    We investigated a dimetallic sulfide endohedral fullerene Sc2 S@C76 which has been synthesized without any characterization in experiments. Our theoretical study reveals that Sc2 S@Td (19151)-C76 which satisfies the isolated-pentagon rule (IPR) possesses the lowest energy, followed by three non-IPR...
  2. Theoretical study on the gas phase reaction of propargyl alcohol with hydroxyl radical.

    Journal Of Computational Chemistry 35(22):1646 (2014) PMID 24995629

    The reaction of propargyl alcohol with hydroxyl radical has been studied extensively at CCSD(T)/aug-cc-pVTZ//MP2/cc-pVTZ level. This is the first time to gain a conclusive insight into the reaction mechanism and kinetics for this important reaction in detail. Two reaction mechanisms were revealed, n...
  3. A two-scale approach to electron correlation in multiconfigurational perturbation theory.

    Journal Of Computational Chemistry 35(22):1609 (2014) PMID 25042641

    We present a new approach for the calculation of dynamic electron correlation effects in large molecular systems using multiconfigurational second-order perturbation theory (CASPT2). The method is restricted to cases where partitioning of the molecular system into an active site and an environment i...

    Journal Of Computational Chemistry 33(26):i (2012) PMID 22961766

    A HOBDI (4-hydroxybenzylidene-1,2-dimethylimidazolinone) solute molecule in aqueous solution was used as one of the test systems to validate the newly implemented quantum-chemical/molecular-mechanical (QM/MM) functionality of the GROMOS (Groningen Molecular Simulation) software for (...

    Journal Of Computational Chemistry 33(24):iii (2012) PMID 22865278

    As presented by Chuan Li, Lin Li, Jie Zhang, and Emil Alexov on page 1960, the image shows the distribution of electrostatic field mapped onto the surface of the adeno-associated virus, PDB ID 3KIC. The structural file, after a standard protonation, contains approximately 484,500 ato...
  6. A simplified homology-model builder toward highly protein-like structures: an inspection of restraining potentials.

    Journal Of Computational Chemistry 33(24):1927 (2012) PMID 22648914

    A homology model builder using simple restraining potentials based on spline-interpolated quadratic functions is developed and interfaced with CHARMM package. The continuity and stability of the potential function were validated, and the parameters were optimized using the CASP7 targ...
  7. Assessment of TD-DFT- and TD-HF-based approaches for the prediction of exciton coupling parameters, potential energy curves, and electronic ...

    Journal Of Computational Chemistry 32(9):1971 (2011) PMID 21484836

    The reliability of linear response approaches such as time-dependent Hartree-Fock (TD-HF) and time-dependent density functional theory (TD-DFT) for the prediction of the excited state properties of 3,4;9,10-tetracarboxylic-perylene-bisimide (PBI) aggregates is investigated. A dimer m...
  8. Accurate bond dissociation enthalpies by using doubly hybrid XYG3 functional.

    Journal Of Computational Chemistry 32(9):1824 (2011) PMID 21455960

    We examine the performance of XYG3, a newly developed doubly hybrid density functional (Zhang, Xu, and Goddard III, Proc Natl Acad Sci USA 2009, 106, 4963), to calculate covalent bond dissociation enthalpy (BDE). We use 5 atoms, 32 molecular radicals, and 116 closed-shell molecules to set up 142 bon...
  9. Performance enhancements for GROMACS nonbonded interactions on BlueGene.

    Journal Of Computational Chemistry 32(9):2041 (2011) PMID 21469156

    Several improvements to the previously optimized GROMACS BlueGene inner loops that evaluate nonbonded interactions in molecular dynamics simulations are presented. The new improvements yielded an 11% decrease in running time for both PME and other kinds of GROMACS simulations that use nonbonded table...
  10. Alkali metal atom-aromatic ring: a novel interaction mode realizes large first hyperpolarizabilities of M@AR (M=Li, Na, and K, AR=pyrrole, i...

    Journal Of Computational Chemistry 32(9):2005 (2011) PMID 21484837

    Several new electride compounds M@pyrrole (M = Li, Na, and K), Li@AR (AR = indole, thiophene, and benzene), Li@tryptophan and Li@serotonin were designed and investigated, which exhibit considerably large first hyperpolarizabilities (β(0) ) (6705, 1116, 11399, 5781, 4808, 1536, 8106,...
