Graph theory is used for modeling, designing, analysis and understanding chemical structures or chemical networks and their properties. The molecular graph is a graph consisting of atoms called vertices and the chemical bond between atoms called edges. In this article, we study the chemical graphs of carbon graphite and crystal structure of cubic carbon. Moreover, we compute and give closed formulas of degree based additive topological indices, namely hyper-Zagreb index, first multiple and second multiple Zagreb indices, and first and second Zagreb polynomials.
图论用于对化学结构或化学网络及其性质进行建模、设计、分析和理解。分子图是一个由原子（称为顶点）和原子之间的化学键（称为边）组成的图。在本文中，我们研究了碳石墨的化学图和立方碳的晶体结构。此外，我们还计算并给出了基于度的加性拓扑指数的封闭公式，即超扎格布指数、第一多重和第二多重扎格布指数以及第一和第二扎格布多项式。
