In Chemical Graph Theory, the topological indices are applied to measure the chemical characteristics of chemical compounds. To the continuity of Kulli’s[21] work on Revan index and by Illic´ and Milosavljevic[9] on weighted vertex szeged index, we introduce the Revan weighted szeged index of graph, which is an another weighted version of szeged index. We present the exact formula of Revan weighted szeged index of corona product of two connected graphs in terms of other graph invariants including the szeged index, first Zagreb index and second Zagreb index. Finally, we apply this result to compute the exact value of Revan weighted szeged indices for some molecular graphs.
