In this paper, a new energy decomposition analysis scheme based on the generalized Kohn-Sham (GKS) and the localized molecular orbital energy decomposition analysis (LMO-EDA) scheme, named GKS-EDA, is proposed. The GKS-EDA scheme has a wide range of DFT functional adaptability compared to LMO-EDA. In the GKS-EDA scheme, the exchange, repulsion, and polarization terms are determined by DFT orbit...

in this study, the interaction between no2+ cation and hen (n = 1-7) clusters is investigated by means of ab initio calculations at mp2/aug-cc-pvtz and qcisd/aug-cc-pvtz computational levels. the first and second solvation shells were obtained while n atom of no2+ interacts with five and two he atoms, respectively. stabilization energies of the studied complexes including basis set superpositio...

In this investigation, the interaction of C20 and Si2H2 molecules was explored in the M06-2X/6-311++G(d,p)level of theory in gas solution phases. The obtained interaction energy values with standard method werecorrected by basis set superposition error (BSSE) during the geometry optimization for all molecules atthe same level of theory. Also, the bonding interaction between th...

In this study the interaction of cis-PtCl2(NH3)2 complex and graphene were investigated with MPW1PW91method in gas and solvent phases. The solvent effect was examined by the self-consistent reaction fieldtheory (SCRF) based on Polarizable Continuum Model (PCM). The selected solvents were chloroform,chlorobenzene, bromoethane, dimethyldisulfide, and dichloroethane. The solvent ...

Intermolecular interactions of different configurations in the HOClO3···CO and HOClO3···H2O dyad and CO···HOClO3···H2O triad systems have been studied at MP2/6-311++G(2d,2p) computational level. Molecular geometries, binding energies, cooperative energies, many-body interaction energies, and Energy Decomposition Analysis (EDA) were eval...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

Water is a small molecule that nevertheless perturbs, sometimes significantly, the electronic properties of an enzyme's active site. In this study, interactions of a water molecule with the ferric heme and the compound I (Cpd I) intermediate of cytochrome P450 are studied. Energy decomposition analysis (EDA) schemes are used to investigate the physical origins of these interactions. Localized m...

An energy decomposition analysis (EDA) method is proposed to isolate physically relevant components of the total intermolecular interaction energies such as the contribution from interacting frozen monomer densities, the energy lowering due to polarization of the densities, and the further energy lowering due to charge-transfer effects. This method is conceptually similar to existing EDA method...

h6-benzne, h6-garphyne) was studied with MPW1PW91 quantum chemical computations. Quantumtheory of atoms in molecules (QTAIM) was applied to elucidate these complexes Cr-CO bonds. Theellipticity (e) and h values of the Cr-CO bonds were calculated. The amount of pp-dp back-donation ofCr-CO bonds were illustrated by calculation of the magnitude of the quadrupole polarization of c...
