DFT study of dimers of dimethyl sulfoxide in gas phase
Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...
متن کاملInterpreting the CO2 adsorption on functionalized organic group of IRMOF-1: A B3LYP DFT based study
Density Functional Theory (DFT) calculations techniques in terms of energetic and electronics properties are used to study CO2 adsorption in NH2-, OH-, COOH-, Br- and Cl-functionalized IRMOF-1. Geometry optimization, density of states (DOS), and energy analyses were performed to investigate the adsorption phenomenon. First, we examined the geometrical as well as the electronic structures of fun...
متن کاملDFT Estimation of Exchange Coupling Constant of Cr8 Molecular Ring using the Hybrid Functional B3LYP
A study of electronic and magnetic properties of an octametallic chromium-based homonuclear molecule Cr8F8(CO2 −C(CH3)3)16 is presented, using density functional theory (DFT) approach and linearized augmented plane wave (LAPW) method with Perdew, Burke and Ernzerhof (PBE) and Becke 3-term correlation (B3LYP) functionals. The exchange coupling parameters between transition metals ions are extrac...
متن کاملDFT Study of 1H-tetrazolyl derivatives of tetrahedrane
Tetrazole-containing compounds have been the subject of much recent research because of theirpotential as high energy density materials (HEDMs). In this work, theoretical studies on the 1Htetrazolylderivatives of tetrahedrane were done at the density functional theory (DFT) method withthe 6-31G(d) basis set without any symmetrical restrictions in order to find the structural andenergetically pr...
متن کاملSystematic investigation of DFT-GIAO 15N NMR chemical shift prediction using B3LYP/cc-pVDZ: application to studies of regioisomers, tautomers, protonation states and N-oxides.
The calculation of 15N NMR chemical shifts has been systematically investigated using density functional theory-gauge including/invariant atomic orbitals (DFT-GIAO) approximation at the B3LYP/cc-pVDZ level of theory. General linear regression terms for 15N chemical shift predictions were calculated for nitromethane and liquid ammonia references in DMSO. Both aliphatic and aromatic nitrogens wer...
