Connection-Based Multiplicative Zagreb Indices of Polycyclic Aromatic Hydrocarbon Structures
Keywords:Zagreb indices, zagreb connection indices, molecular graphs, topological index
The topological index (TI) is a numerical value that is linked to a graph and explains its diverse chemical and physical characteristics. The first distance-based TI was created by Wiener to establish the boiling point of paraffin. In 1972, degree-based indices were introduced to evaluate the overall π-electron energy of molecules in a molecular graph. This study focuses on three distinct types of polycyclic aromatic hydrocarbon structures, namely Hexa-peri-hexabenzocoronene, Dodeca-benzo-circumcoronene, and Hexa-cata-hexabenzocoronene, utilizing various multiplicative Zagreb indices based on connection numbers.
