Definition and application of topological index based on bond connectivity

Abstract

Bond connectivity topological index S_i based on chemical bonds was defined by using a matrix method. And S_i is formed by atomic parameters such as the number of valence electrons, the number of the highest main quantum of atoms and the bonding electrons and bond parameters such as the length of bonds, the electronegativity difference of bonding atoms. The molecular bond connectivity topological index S is composed of S_i. The thermodynamic properties of saturated hydrocarbons, unsaturated hydrocarbons, oxygen organic, methane halide and transitional element compounds and the molecular bond connectivity topological index S have an optimal correlative relationship.

Keywords
