Chemical bond analysis in the ten-electron series
This thesis presents briefly the application of quantum mechanics on systems of chemical interest, i.e., the field of quantum chemistry and computational chemistry. The molecules of the ten-electron series, hydrogen fluoride, water, ammonia, methane and neon, are taken as computational examples. Some applications of quantum chemistry are then shown on these systems, with emphasis on the nature ...
متن کاملElectron–electron interactions in the chemical bond: “1/3” Effect in the bond length of hydrogen molecule
The prominent “1/3” effect observed in the Hall effect plateaus of twodimensional electron gas (2DEG) systems has been postulated to indicating 1/3 fractional charge quasiparticle excitations arising from electron–electron interactions. Tunneling shot-noise experiments on 2DEF exhibiting fractional quantum Hall effect (FQHE) shows evidence for tunnelling of particles with e and e/3 charges for ...
متن کاملThe Chemical Bond
Theories of the chemical bond aim to explain the structures and stabilities of molecules, and different theories aim for different levels of explanation. The most important theories are those that give simple explanations for the structures and stabilities of the most stable molecules ; broadly speaking, those that we find in bottles on the shelf of a laboratory. However, as experimental chemis...
متن کاملThe Representation of the Chemical Bond in Quantum Chemical Calculations
The mathematical representation of chemical bonds in molecules is discussed. The molecule is viewed as a system of weakly interacting chemical bonds. The intrabond problems and the averaged electrostatic interbond interactions are handled at the . zeroth order, while the small interbond delocalization and dispersion effects are taken into account on the basis of the perturbation theory. A speci...
متن کاملA Description of the Chemical Bond in Terms of Local Properties of Electron Density and Energy
Chemical bonding is described in terms of the properties of the one-electron density f2 (r) and the local energy density H (r) = G (r) + V (r). Analysis of a variety of different bonds suggests that covalent bonding requires the existence of ao saddle point rP of f2 (r) in the internuclear region (necessary condition) and a predominance of the local potential energy V (r) at r P : J VP J > GP a...
