Antiferromagnetism

In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions.

See 5-Dehydro-m-xylylene and Antiferromagnetism

Aromaticity

In organic chemistry, aromaticity is a chemical property describing the way in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibits a stabilization stronger than would be expected by the stabilization of conjugation alone.

See 5-Dehydro-m-xylylene and Aromaticity

Electron configuration

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.

See 5-Dehydro-m-xylylene and Electron configuration

Ground state

The ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system.

See 5-Dehydro-m-xylylene and Ground state

Hund's rule of maximum multiplicity

Hund's rule of maximum multiplicity is a rule based on observation of atomic spectra, which is used to predict the ground state of an atom or molecule with one or more open electronic shells.

See 5-Dehydro-m-xylylene and Hund's rule of maximum multiplicity

Molecular orbital

In chemistry, a molecular orbital is a mathematical function describing the location and wave-like behavior of an electron in a molecule.

See 5-Dehydro-m-xylylene and Molecular orbital

Non-Kekulé molecule

A non-Kekulé molecule is a conjugated hydrocarbon that cannot be assigned a classical Kekulé structure.

See 5-Dehydro-m-xylylene and Non-Kekulé molecule

Organic chemistry

Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

See 5-Dehydro-m-xylylene and Organic chemistry

Radical (chemistry)

In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron.

See 5-Dehydro-m-xylylene and Radical (chemistry)

Spin (physics)

Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms.
