Linear combination of atomic orbitals molecular orbital method — A linear combination of atomic orbitals or LCAO is a quantum superposition of atomic orbitals and a technique for calculating molecular orbitals in quantum chemistry [Huheey, James. Inorganic Chemistry:Principles of Structure and Reactivity ] .… … Wikipedia
Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… … Wikipedia
Molecular orbital — See also: Molecular orbital theory In chemistry, a molecular orbital (or MO) is a mathematical function describing the wave like behavior of an electron in a molecule. This function can be used to calculate chemical and physical properties such… … Wikipedia
Molecular orbital diagram — A molecular orbital diagram, or MO diagram for short, is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the Linear combination of atomic orbitals molecular orbital… … Wikipedia

Molecular orbital theory — In chemistry, molecular orbital (MO) theory is a method for determining molecular structure in which electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole… … Wikipedia
molecular orbital — noun The quantum mechanical behaviour of an electron in a molecule describing the probability of the electrons particular position and energy; approximated by a linear combination of atomic orbitals … Wiktionary
Molecular symmetry — in chemistry describes the symmetry present in molecules and the classification of molecules according to their symmetry. Molecular symmetry is a fundamental concept in chemistry, as it can predict or explain many of a molecule s chemical… … Wikipedia
Slater-type orbital — Slater type orbitals (STOs) are functions used as atomic orbitals in the linear combination of atomic orbitals molecular orbital method. They are named after the physicist John C. Slater, who introduced them in 1930 [J.C. Slater, Atomic Shielding … Wikipedia
Non-bonding orbital — A non bonding orbital, also known as non bonding molecular orbital (NBMO) and sometimes designated by the letter n in molecular orbital diagrams, is a molecular orbital whose occupation by electrons neither increases nor decreases the bond order… … Wikipedia
Chemical bond — A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges, either between electrons and… … Wikipedia
