Die Triplettzustande von 4nπ-Elektronen-Annulenen sollten, wie Baird 1972 vorgeschlagen hatte, eher als aromatisch denn als antiaromatisch betrachtet werden. Diese Triplettzustande haben planare, symmetrische Geometrien (wie bei C9H9+, siehe rechts), viel niedrigere Energien als die entsprechenden Triplett-Referenzzustande und weisen nach Rechnungen, in denen die Wechselwirkungen mit den ungepaarten Elektronen vernachlassigt werden, diatrope Ringstrome auf (kernunabhangige chemische… Expand

A preferred disrotatory 4n electron Möbius aromatic transition state for a thermal electrocyclic reaction.
Not forbidden: Thermal 4n electron electrocyclic reactions of Hückel topology structures proceed via "allowed" conrotatory pathways. However, for a Möbius topology, the Woodward-Hoffmann rules may beExpand

Triplet-state aromaticity of 4npi-electron monocycles: analysis of bifurcation in the pi contribution to the electron localization function.
The pi contribution to the electron localization function (ELF) is used to compare 4npi- and (4n+2)pi-electron annulenes, with particular focus on the aromaticity of 4npi-electron annulenes in theirExpand
Scope and limitations of Baird's theory on triplet state aromaticity: application to the tuning of singlet-triplet energy gaps in fulvenes.
TLDR
It is shown that the singlet-triplet energy gaps of pentafulvenes are easily varied through substitution by as much as 36 kcal mol(-1) and that triplet-state aromaticity can greatly influence the properties of conjugated compounds in the T1 state. Expand

Demonstration of "Möbius" aromaticity in planar metallacycles.
TLDR
This work reports the first computationally confirmed 4npi aromatic planar metallacyclic examples and their building principles, and the role of wave function boundary conditions (periodic vs. antiperiodic) in chemistry is further stressed. Expand

Analysis of a Compound Class with Triplet States Stabilized by Potentially Baird Aromatic [10]Annulenyl Dicationic Rings.
TLDR
The low-lying triplet state of a recently published compound (TMTQ) was analyzed quantum chemically in light of suggestions that it is influenced by Baird aromaticity, and it is found that TMTQ and its analogues are Hückel-Baird hybrids allowing for tuning between closed-shell 4n+2 HüCkel aromaticity and open- shell 4n Baird aromaticality.

Magnetic Shielding, Aromaticity, Antiaromaticity and Bonding in the Low-Lying Electronic States of S2 N2.
TLDR
The results strongly suggest that S2 N2 is the first example of an inorganic ring for which theory predicts substantial changes in aromaticity upon vertical transition from the ground state to the first singlet excited or lowest triplet electronic states. Expand
