Abstract :The harmonic i index of graph $G$ is defined as the sum $H(G)=\sum\limits_{ij\in E(G)}\frac{2}{d_{G}(i)+d_{G}(j)}$, where $d_{G}(i)$ is the degree of a vertex $i$ in $G$. In this paper we examined eccentric version of harmonic index of graphs.Keywords : Topological Index, Graph Parameters, Harmonic Index.
