  Article:   COMPUTATION OF ECCENTERIC CONNECTIVITY AND RANDIĆ INDICES OF SOME BENZENOID GRAPHS.

Authors:  .
 
       
         
  Abstract:  Chemical compounds are often modeled as polygonal shapes, where a vertex represents an atom and an edge symbolizes a bond. A topological index is a number related to a molecular graph invariant. In this paper, exact formulas for the eccentricic connectivity and Randić indices of hexagonal parallelogram of benzenoids are given.

Keywords: Eccentric connectivity, Randić index, hexagonal parallelogram Benzenod, Nanotorus.
