A quantum description using one-electron functions delocalized over a molecule as a basis for its many-electron state.

This is an authored directed relation from the source endpoint to the target endpoint.
Molecular-orbital models represent cyclic delocalization associated with aromaticity, but energetic, magnetic, structural, and reactivity criteria need not agree in marginal cases.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

Molecular-orbital theory models metal–ligand bonding through symmetry-adapted donor and acceptor interactions; the chosen orbital partition is model dependent and correlation may require extensions.

This is an authored directed relation from the source endpoint to the target endpoint.
Molecular-orbital theory describes bonding through occupations of orbitals extending over the molecular framework.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
wp-physics-chemical-bondopenstax-chemistry-2eiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Molecular-orbital theory labels pi orbitals and their bonding combinations by the nodal plane containing the internuclear axis, providing a symmetry-based description that need not imply localized electron pairs.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
wp-physics-chemical-bondopenstax-chemistry-2eiupac-chemical-bondThis is an authored directed relation from the source endpoint to the target endpoint.
Molecular-orbital theory is one central approximation framework within quantum chemistry, not an observable decomposition of an exact many-electron state.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-physics-chemical-bondopenstax-chemistry-2eiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Molecular-orbital theory labels orbitals and bonding combinations by their symmetry relative to the internuclear axis, yielding sigma and pi bonding descriptions within the model.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
