One cannot turn this model around and argue that the observation of a certain geometry demonstrates the existence of the electron pairs. Besides, such circularism begs the question as to what the electron pair is.doi:10.1007/978-94-009-2853-4_4R. F. W. BaderSpringer Netherlands
62) The real system׳s pair density is modeled as the uncorrelated value plus a correction: (3)Γ(r→1,r→2)=12ρ(r→1)(ρ(r→2)+hXC(r→1,r→2)) The electron repulsion energy becomes the uncorrelated (Hartree) term, plus an exchange-correlation density functional (XC functional)...
Because of the formation of HBs, most of the water molecules concentrate close to the free electron pair of the nitrogen atom. There are also high concentrations above and below the aromatic ring. When the molecule is excited, part of the charge is transferred from the nitrogen atom to the ...
d Temperature dependence of the TEF peaks for a nozzle pair with 2 µm separation. Inset: peak height of the primary peak scaled by its value at 2 K as a function of temperature. The decay of the peak follows the reduction in mean-free path Full size image TEF as a probe of ...
(Fig.1a). Such a geometry allows us to study the impact of the self-affine scaling of the Si/SiO2roughness on qubit properties at different length-scales30(Fig.1b). Starting from a detailed view to the device architecture, quantum dot formation, and materials interface down to the atomic ...
The term “crystallized electron pair” is understood to be a stationary, quantum particle build of two bound electrons that exist in a quantum state having charge −2e and integer spin. The term “stable free electron in conducting condensed matter” is understood to include a stationary quantu...
This very simple approach, which is widely used in Organic Chemistry nowadays, was employed in the 1950s to establish important organic reactivity models such as the Frontier Molecular Orbital (FMO) theory [17] for the study of the reactivity in Organic Chemistry [18]. Molecular geometry ...
The interaction that is different from the covalent bond comes from the shared electron pair, so there is no electron accumulation in the bonding area. The increase in the degree of aggregation will reduce the surging ability of electrons and weaken the role of electrons in the electrostatic ...
