Minimum Number of Kekulé Structures of Certain Benzenoid Graphs and -Polyacenic Nanotubes

Polycyclic aromatic compounds (Print), 2022
In a molecular graph, a Kekulé structure and perfect matching resembles the same. Thus, the number of Kekulé structure(chemically) is equal to the number of perfect matching (mathematically) required to cover the edge set or covalent bonds of a molecular

Kekulé structures of honeycomb lattice on Klein bottle and Möbius strip

, 2021
In organic chemistry, there are strong connections between the number of the Kekule structures and chemical properties for many molecules. In this paper, we focus on some honeycomb lattices on Klein bottle and Mobius strip. We obtain explicit expressions
