Chemical graph theory has become a prime gadget for mathematical chemistry due to its wide range of graph theoretical applications for solving molecular problems. A numerical quantity is named as topological index which explains the topological characteristics of a chemical graph. Recently face centered cubic lattice FCC ( n ) attracted large attention due to its prominent and distinguished properties. Mujahed and Nagy (2016, 2018) calculated the precise expression for Wiener index and hyper-Wiener index on rows of unit cells of FCC ( n ). In this paper, we present the ECI (eccentric-connectivity index), TCI (total-eccentricity index), CEI (connective eccentric index), and first eccentric Zagreb index of face centered cubic lattice.

面心立方晶格FCC（n）的基于偏心率的拓扑指数

化学图论因其广泛的解决分子问题的图论应用而成为数学化学的主要工具。数值量被称为拓扑指数，它解释了化学图的拓扑特征。最近，面心立方晶格FCC（n）由于其突出和杰出的性能而引起了广泛的关注。Mujahed和Nagy（2016，2018）计算了FCC单位单元行上Wiener指数和hyper-Wiener指数的精确表达式（n）。在本文中，我们介绍了面心立方晶格的ECI（偏心连接指数），TCI（总偏心指数），CEI（连接偏心指数）和第一偏心Zagreb指数。
