abstract = {Phenacenes are a group of organic compounds that consist of fused aromatic rings. They also follow the general molecular formula C4n+2H2n+4. In this article, we compute the SMP polynomial for phenacenes with even and odd numbers of rings. Then, through these polynomials, we obtain general formulas for topological indices based on distances such as Sz, PI, and Mo. Using these formulas does not require counting the edges, and these indices are calculated according to the number of benzene rings in phenacenes. We display the obtained results numerically and graphically and compare topological indices graphically.}
