On Molecular Descriptors of Polycyclic Aromatic Hydrocarbon

A molecular descriptor is a real valued number related to a molecular graph and is a structural invariant. Molecular Descriptors(Topological Indices) are the significant numerical quantities in the fields of chemical graph theory. Quantitative structure-property relationships (QSPR)and structure-activity relationships (SAR) of the polycyclic aromatic hydrocarbon compounds necessitate expressions for the molecular topological features of these compounds. Topological indices are vital devices for investigating chemical compounds to comprehend the fundamental topology of chemical structures. Ev-degree and ve-degree based topological indices are two novel degrees based indices as of late defined in graph theory. Ev-degree and ve-degree based molecular descriptor (topological indices) have been defined as corresponding to their relating partners. In this paper, we have computed topological indices based on ev-degree and ve-degree for the Polycyclic Aromatic Hydrocarbon (PAHn).
