摘要

Graph theory is an essential tool within theoretical chemistry, and the subdiscipline of chemical graph theory applies graph-theoretical ideas to understand structure and reactivity in chemical systems. In this paper, we calculate and compare some distance-based topological indices on the Starphene and Stellated Starphene molecular graphs. Indices considered are the Wiener index, multiplicative Wiener index, hyper-Wiener index, and Harary index, which account for structural properties as well as chemical reactivity of these molecules. We used MATLAB to compute these indices and represented distance and adjacency matrices. The results enrich our knowledge of the structural characteristics and applications of Starphene and Stellated Starphene graphs in chemical graph theory.
