چکیده

Simple analytical functional forms for the electron density of twoand Ž . three-electron atoms which reproduce fairly the correlated exact values are presented. Ž . The procedure is based on the fitting of an auxiliary f r function which has adequate properties for this purpose and can be extended to more complex atoms. Q 1999 John Wiley & Sons, Inc.

Enhancement factors for positron annihilation studies

Electron and positron densities for a number of positron binding atoms and ions are used to benchmark methods used to compute positron annihilation rates in solids. The electron and positron densities from ab initio calculations are multiplied by some commonly used enhancement factors and integrated to give the annihilation rate. These are then compared with the close to exact annihilation rate...

Theoretical studies on corrosion inhibition of N-aroyl-N’-aryl thiourea derivatives using conceptual DFT approach

In this paper, quantum chemical parameters at density functional theory (DFT) B3LYP/6-31G** (d,p) level of theory were calculated for three organic corrosion inhibitors [N-benzoyl-N-(p-aminophenyl) thiourea, N-benzoyl-N-(thiazole) thiourea and N-acetyl-N-(dibenzyl) thiourea. The calculated molecular descriptors such as the HOMO, LUMO, dipole moment, chemical potential (μ), chemical hardness (ղ)...

On the relationship between densities of Shannon entropy and Fisher information for atoms and molecules.

An analytical relationship between the densities of the Shannon entropy and Fisher information for atomic and molecular systems has been established in this work. Two equivalent forms of the Fisher information density are introduced as well. It is found that for electron densities of atoms and molecules the Shannon entropy density is intrinsically related to the electron density and the two for...

Investigation of Nickle nanoclusters properties by density functional theory

Clusters play important role for understanding and transferring microscopic to macroscopic properties.Geometric and electron properties of Small nickel clusters up to the tetramer has been investigated by Density Functional Theory (DFT). Raising the number of nickel clusters atoms were indicated decreasing the average equilibrium (Ni-Ni) distance of atoms and also the binding energy of per atom...

Computational studies of planar, tubular and conical forms of silicon nanostructures

Density functional theory (DFT) calculations were performed to investigate the properties of planar, tubular and conical forms of silicon nanostructures. The evaluated parameters including averaged bond lengths, binding energies, gap energies and dipole moments were then evaluated for the optimized models of study. The results indicated that the bond lengths between silicon atoms are different ...
