Equiseparability on Terminal Wiener Index and Distances

Teminal Wiener index is one of the commonly used topological index in mathematical chemistry. If two or more chemical compounds have the same terminal Wiener index then they will have similar physico-chemical properties. In this work we propose a new method for constructing equiseparable trees w.r.t terminal Wiener index. The existing method is based on the number of pendent vertices but the proposed method is based on distance parameters.
