For a connected graph G , the Hosoya polynomial of G is defined as H ( G, x ) = ∑ { u,v }⊆ V ( G ) x d ( u, v ) , where V ( G ) is the set of all vertices of G and d ( u,v ) is the distance between vertices u and v . In this article, we obtain analytical expressions for Hosoya polynomials of TUC 4 C 8 ( R ) nanotubes. Furthermore, the Wiener index and the hyper‐Wiener index can be calculated. © 2008 Wiley Periodicals, Inc. Int J Quantum Chem, 2009
