Magnetic couplings mediated through the non-covalent interactions
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Density functional theory (DFT), broken symmetry (BS) approach, was applied in order to determine the mechanism of couplings through the non-covalent interactions for the series of coordination compounds bridged by strong ...
Solvent and structural effects in tautomeric 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridones: experimental and quantum chemical study
(Springer/Plenum Publishers, New York, 2014)
The tautomeric equilibria between 2-pyridone and 2-hydroxypyridine forms of methoxy, chloro, and nitro derivatives of 3-cyano-4-(2-, 3-, and 4-substituted phenyl)-6-phenyl-2(1H)-pyridones were evaluated from UV/Vis spectral ...
Computational study of protein secondary structure elements: Ramachandran plots revisited
(Elsevier Science Inc, New York, 2014)
Potential energy surface (PES) were built for nineteen amino acids using density functional theory (PW91 and DFT M062X/6-311**). Examining the energy as a function of the phi/psi dihedral angles in the allowed regions of ...
Solvent and structural effects in tautomeric 2(6)-hydroxy-4-methyl-6(2)-oxo-1-(substituted phenyl)-1,2(1,6)-dihydropyridine-3-carbonitriles: UV, NMR and quantum chemical study
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The state of the tautomeric equilibria of 2(6)-hydroxy-4-methyl-6(2)-oxo-1-(substituted phenyl)-1,2(1,6)-dihydropyridine-3-carbonitriles, 2-PY/6-PY, was evaluated using experimental and theoretical methodology. The ...
Exploring the applicability of density functional tight binding to transition metal ions. Parameterization for nickel with the spin-polarized DFTB3 model
(Journal of Computational Chemistry, 2019)
In this work, we explore the applicability and limitations of the current third order density functional tight binding (DFTB3) formalism for treating transition metal ions using nickel as an example. To be consistent with ...
