On the π-Electron Content of Rings in Benzenoid Parallelograms
نویسنده
چکیده
We make use of the classical correspondence between Kekulé structures and lattice paths to obtain explicit formulas for the Pauling bond order of edges in benzenoid parallelograms. These formulas are further used to establish the average π-electron content of hexagonal rings in such benzenoids. We then compare this quantity with the atom-based π-electron content of rings, and study the local and the asymptotic behaviour of their difference.

Effects of Structure and Partially Localization of the π Electron Clouds of Single-Walled Carbon Nanotubes on the Cation-π Interactions
A C102H30 graphene sheet has been rolled up to construct Single-Walled Carbon NanoTube Fragments (SWCNTFs) as parts of armchair carbon nanotubes by computational quantum chemistry methods. Non-covalent cation-π interactions of the Na+ cation on the central rings of SWCNTFs have investigated. The binding energies of the Na+-SWCNTF complexes versus ...
متن کاملEffects of structure and number of Heteroatom on the π-π stacking interactions of benzene with N-substituted coronenes: A theoretical study
Stability of the π-π stacking interactions in the Ben||N-substituted-coronene complexes was studied using the computational quantum chemistry methods (where Ben is benzene and || denotes π-π stacking interaction, and N-substituted-coronene is coronene molecule which substituted with different number of N atoms). The results reveal simultaneous effects of structure and number of Heteroatom on th...
متن کاملEquivalence of Two Models for Partitioning of π-Electrons in Rings of Benzenoid Hydrocarbons
Kekulé structures belong to the classical concepts of theoretical chemistry of polycyclic conjugated molecules and, in particular, of benzenoid hydrocarbons [1 – 3]. Nevertheless, it was only quite recently recognized [4] that in addition to the standard representation of a Kekulé structure (in which the locations of the double bonds are indicated), also an “algebraic” representation is possibl...
متن کاملPerfect Matchings in Polyhexes, or Recent Graph-theoretical Contributions to Benzenoids
After an introduction on the history of polycyclic aromatic compounds, recent advances in the theory of benzenoids are briefly reviewed. Then using systems with 4, 5, or 6 benzenoid rings for illustration, the partition of the P π-electrons among the rings of the benzenoid is presented, followed by a different way of examining the distribution of these π-electrons which is called the signature ...

In its crystal structure, the title compound, C(9)H(7)NO(3), forms π-stacked dimers, with a centroid-centroid distance of 3.475 (5) Å between the benzenoid and the 2,4 dicarbonyl oxazine rings. These dimers then form staircase-like linear chains through further π-stacking between the benzenoid rings [centroid-centroid distance of 3.761 (2) Å]. The methyl-H atoms are disordered due to rotation a...
