A conceptual framework chemistry of Hydrated Cations: Part I. Preliminary Ab Initio and QTAIM calculations on [Li(H20)nr (n=1,2,3).
Ion molecules with general chemical formula as [Li(H2O)] (n=1,2,3), have been chosen as model species toinvestigate the chemical properties of hydrated lithium cations. The RHF(SCVS)/UGBS level of calculationhas been used for obtaining equilibrium geometries and Rho(r) functions (electron density distributions). By theaid of fundamental physical theorems implemented in Quantum Theory of Atoms i...
متن کاملAb Initio Evaluation of Plasmon Lifetimes in the Alkali Metals
The anomalous plasmon linewidth dispersion (PLD) measured in K by vom Felde, Sprösser-Prou, and Fink (Phys. Rev. B 40, 10181 (1989)), has been attributed to strong dynamical electron-electron correlations. On the basis of ab initio response calculations, and detailed comparison with experiment, we show that the PLD of K is, in fact, dominated by decay into particle-hole excitations involving em...
متن کاملEngineering energy gap of the carbon saturated nanowire and investigating the ammonia molecule doping effects by using the initial calculations (Ab initio)
In this paper size effects, growth orientation and also doping by Ammonia molecule (NH3) on the carbon nanowire properties with saturated diamond structure by (DNw:H) have been investigated. This study was carried out using DFT theory and Kohn-Sham equation by self-consistent field (SCF) that performed by local density approximation (LDA). The nanowires morphology is cylindrical with [111] grow...
متن کاملAb initio study of collective excitations in a disparate mass molten salt.
Ab initio molecular dynamics simulations and the approach of generalized collective modes are applied for calculations of spectra of longitudinal and transverse collective excitations in molten LiBr. Dispersion and damping of low- and high-frequency branches of collective excitations as well as wave-number dependent relaxing modes were calculated. The main mode contributions to partial, total, ...
متن کاملElectronic states of the Cr2O3(0001) surface from ab initio embedded cluster calculations
The electronic structure of the Cr2O3(0001) surface is studied by means of ab initio embedded cluster calculations. Charge distributions and local d–d excitations are analysed for different geometrical relaxations of the surface. In the ground state there is considerable delocalization of electrons from the oxygen 2p band into the partly occupied 3d AOs of the Cr cations at the surface such tha...
