Localization of electrons
Witryna22 sty 2004 · The electron localization function (ELF) has been separated in its sigma and pi components. The topological analysis of the new ELFsigma and ELFpi functions has been used to quantify the concept of resonance. The highest bifurcation values of these functions describe in a correct way the aromaticity of classical ring molecules … Witryna17 paź 2024 · The electron localization function (ELF) was introduced by Becke and Edgecombe as a "simple measure of electron localization in atomic and molecular …

In a regular lattice, these states are non-localized Bloch functions, forming a band of width B, say. Attention is focused on the effects of `cellular disorder', where a statistical variation wl is imposed on the energy …
