Electron Density Definition in Chemistry - ThoughtCo

Electron density or electronic density is the measure of the probability of an electron being present at an infinitesimal element of space surrounding any given point. It is a scalar quantity depending upon three spatial variables and is typically denoted as either $${\displaystyle \rho ({\textbf {r}})}$$ Ver mais The electronic density corresponding to a normalised $${\displaystyle N}$$-electron wavefunction $${\displaystyle \Psi }$$ (with $${\displaystyle {\textbf {r}}}$$ and $${\displaystyle s}$$ denoting spatial and spin variables … Ver mais From its definition, the electron density is a non-negative function integrating to the total number of electrons. Further, for a system with kinetic … Ver mais In molecules, regions of large electron density are usually found around the atom, and its bonds. In de-localised or conjugated systems, such as phenol, benzene and compounds such as hemoglobin and chlorophyll, the electron density is significant … Ver mais • Difference density map • Electron cloud • Electron configuration • Resolution (electron density) • Charge density Ver mais Another more-general definition of a density is the "linear-response density". This is the density that when contracted with any spin-free, … Ver mais Many experimental techniques can measure electron density. For example, quantum crystallography through X-ray diffraction scanning, … Ver mais Spin density is electron density applied to free radicals. It is defined as the total electron density of electrons of one spin minus the total electron density of the electrons of the other spin.
