Few concepts are as frequently used as aromaticity in the current chemical literature. 1 This
may be quantified by ca. 300 000 papers dealing with the aromatic properties of chemical …

The problem of localized versus delocalized bonding is almost as old as chemical structure
theory itself. The theory of localized bonding in organic molecules was introduced by …

Aromaticity, 1 one of the most important concepts in chemistry, is confined not only to planar
twodimensional (2D) molecules but also can be extended to diverse structures of other …

The components of nucleus-independent chemical shift (NICS) tensors for Dnhn-annulenes
are discussed as indexes of the aromatic character of electronic π systems. The component …

In 1747, Johann Sebastian Bach wrote a series of canons and fugues on the occasion of his
visit to King Frederick the Great of Prussia in Potsdam. His music of homage, the …

Chemists have been fascinated for a long time with electron delocalization in covalently
linked molecules, and especially with the prototypical phenomenon of aromaticity. Even …

Branched alkanes like isobutane and neopentane are more stable than their straight chain
isomers, n‐butane and n‐pentane (by 2 and 5 kcal mol− 1, respectively). Electron …

The synthesis and X-ray characterization of two new dialkynylated diazatetracenes and the
corresponding N, N-dihydrodiazatetracenes are reported. The dialkynylated heteroacenes …

The Second Edition demonstrates how computational chemistry continues to shed new light
on organic chemistry The Second Edition of author Steven Bachrach's highly acclaimed …

The geometries of four different series of D 6 h-symmetric polybenzenoid hydrocarbons
(PBH) up to and including C222H42 have been optimized at the B3LYP/6-31G (d) level of …
