The transformations that leave a molecular geometry or molecular Hamiltonian invariant, organized through point or permutation-inversion groups.

This is an authored directed relation from the source endpoint to the target endpoint.
Idealized and distorted coordination geometries can be classified by molecular symmetry, constraining orbitals, spectra, and isomerism.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-inorganic-chemistryiupac-red-bookiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Molecular point-group operations act on nuclear coordinates, orbitals, and normal modes; the resulting representations classify states and constrain spectral selection rules.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.

A rigid molecular structure is chiral when its symmetry lacks operations that superpose it on its mirror image; conformational motion can change the relevant description.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-organic-chemistryiupac-blue-bookpubchem-docsThis is an authored directed relation from the source endpoint to the target endpoint.
A molecular geometry is classified by symmetry operations that leave the idealized nuclear arrangement invariant; conformational motion, isotopic substitution, and environment can lower the effective symmetry.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-physics-chemical-bondopenstax-chemistry-2eiupac-gold-bookEach relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Molecular symmetry classifies states and normal modes and constrains which transitions can carry intensity.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
