RoumenaSrtt Univ.M. GhorbaniDepartment of mathematics, Shahid Rajaee Teacher Training UniversityJournal Article20140214In theoretical chemistry, molecular structure descriptors are used to compute properties of chemical compounds. Among them Wiener, Szeged and detour indices play significant roles in anticipating chemical phenomena. In the present paper, we study these topological indices with respect to their difference number.http://ijmc.kashanu.ac.ir/article_7776_399fb4dba96bdfcaab0aa600fba7f2f6.pdf
