摘要：
TUC4C8(S) nanotubes belong to important and extensively studied compounds in materials science. Topological indices are extensively used for establishing relationships between the structure of nanotubes and their physico-chemical properties. These nanotubes can be represented by graphs which consist of vertices and edges. Several researchers studied one or a few chosen topological indices for TUC4C8(S) nanotubes. We obtained a general formula presented in our first theorem. The importance of our formula is that it is not necessary to do a complicated investigation in order to find one particular degree-based index for TUC4C8(S) nanotubes. It suffices to take the definition of a particular index and use it our formula. We used our formula to obtain the second theorem containing the most well-known indices for TUC4C8(S) nanotubes.
