摘要
In chemistry, topological descriptors have a prominent role; also connectivity indices are very important in chemical graph theory. Chemical graph theory is helpful to understand about the structural properties of a molecular graph. In this article, we study the chemical graphs of copper oxide and carbon graphite and we compute and give close formulas of eccentricity based topological indices, such as total eccentricity index and average eccentricity index for chemical graphs of carbon graphite and copper oxide.
