In quantum chemical calculations, the electron density, ρ (r), is a function of the coordinates r, defined so ρ (r)d r is the number of electrons in a small volume d r. For closed-shell molecules, can be written in terms of a sum of products of basis functions, φ:
9 lip 2019 · Electron density is a representation of the probability of finding an electron in a specific location around an atom or molecule. In general, the electron is more likely to be found in regions with high electron density.
Electron density is a fundamental concept in quantum mechanics that describes the probability distribution of electrons within an atom or molecule. It is a crucial factor in understanding the behavior and properties of chemical systems.
In Density Functional Theory (DFT), electron density is the central variable, allowing for the calculation of various molecular properties and energies without needing to solve the many-body Schrödinger equation directly.
1 sie 2024 · In this article we will analyze the two main interpretations of the concept of electron density: the Born-style probability density interpretation and the Schrödinger-style charge density interpretation.
15 lis 2011 · Because in chemical reactions, electrons will flow from areas of high electron density to areas of low electron density. Knowing where the partial charges are is an important first step in determining where the molecule will react.
