Vertex-degree-based molecular structure descriptors of benzenoid systems and phenylenes [PDF]
Journal of the Serbian Chemical Society, 2012 Several recently published papers report expressions for various vertex-degree-based molecular structure descriptors of benzenoid systems and phenylenes. We deduce here the general expression for these descriptors, and show that a simple and generally

Analysis of irregularity measures of zigzag, rhombic, and honeycomb benzenoid systems
Open Physics, 2020 Molecular topology is a key to determine the physiochemical aspects of the molecular structure. To determine the degree of irregularity of a certain molecular structure or a network has been a key source of interest for the molecular topologists as it ...

On Computation and Analysis of Topological Index-Based Invariants for Complex Coronoid Systems
Complexity, 2021 In chemical graph theory, benzenoid systems are interrogated as they exhibit the chemical compounds known as benzenoid hydrocarbons. Benzenoid schemes are circumscribed as planar connected finite graphs having no cut vertices wherein the entire internal ...

An induced P3 packing k-partition number for Benzenoid system [PDF]
Mathematics and Computational SciencesBenzenoid systems are formed by collections of congruent hexagons arranged in the plane such that any two hexagons are either disjoint or share a common edge. These structures are naturally studied through graph-theoretic packing parameters.

From Static to Dynamic: Electron Density of HOMO at Biaryl Linkage Controls the Mechanism of Hole Delocalization [PDF]
, 2018 In order to extend the physical length of hole delocalization in a molecular wire, chromophores of increasing size are often desired. However, the effect of size on the efficacy and mechanism of hole delocalization remains elusive.

Spectral studies of some hydroxy-derivatives of anthraquinones [PDF]
, 1970 The u.v., visible, and i.r. spectra of several hydroxy-anthraquinones are discussed and the bands are assigned. These bands are compared with those of anthracene and anthraquinone. The band at 207 nm.

Molecular descriptors of benzenoid systems
Química Nova, 2016 Molecular descriptors are being widely used in QSAR/QSPR studies in chemistry and drug designing as well as modeling of compounds. Different topological descriptors have been formulated to investigate the physio chemical properties and chemical reactivity of compounds.
