Electron Energy Studying of Molecular Structures via Forgotten Topological Index Computation

Journal of Chemistry, 2016
It is found from the earlier studies that the structure-dependency of total π-electron energy Eπ heavily relies on the sum of squares of the vertex degrees of the molecular graph. Hence, it provides a measure of the branching of the carbon-atom skeleton.
