Aromaticity is one of the most deeply rooted concepts in chemistry. But why, if two-thirds of
existing compounds can be classified as aromatic, is there no consensus on what …

Steric indices are parameters used in chemistry to describe the spatial arrangement of
atoms or groups of atoms in molecules. They are important in determining the reactivity …

3D-aromatic molecules with (distorted) tetrahedral, octahedral, or spherical structures are
much less common than typical 2D-aromatic species or even 2D-aromatic-in-3D systems …

A 2D map is created for solid‐state materials based on a quantum‐mechanical description
of electron sharing and electron transfer. This map intuitively identifies the fundamental …

Conspectus The ring currents of aromatic and antiaromatic molecules are remarkable
emergent phenomena. A ring current is a quantum-mechanical feature of the whole system …

Gain of aromaticity or relief of antiaromaticity along a reaction path are important factors to
consider in mechanism studies. Analysis of such changes along potential energy surfaces …

Aromaticity and Antiaromaticity A comprehensive review of the science of aromaticity, as
well as its evolution, from benzene to atomic clusters In Aromaticity and Antiaromaticity …

Magnetically induced ring currents are a conventional tool for the characterization of
aromaticity. Dia-and paratropic currents are thought to be associated with stabilization …

An alternative response function, based on the dual descriptor in terms of Koopmans'
approximation, is hereby proposed for the description of chemical reactivity in systems with …

From time to time I have the opportunity to give lectures on topics related to aromaticity.
Quite often in these occasions I get comments from the audience complaining about the fact …
