Enhanced cyclic delocalization and associated energetic, magnetic, structural, and reactivity patterns under an explicitly stated aromaticity criterion.

This is an authored directed relation from the source endpoint to the target endpoint.
A conjugated heterocycle can be assigned aromatic character using explicit energetic, structural, magnetic, or electronic criteria; heteroatom participation and state can change the assessment.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

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.

Resonance contributors model aspects of aromatic delocalization, but aromaticity is multidimensional and also assessed through energetic, structural, magnetic, and reactivity criteria.
