Graphical indices are applied to measure to chemical characteristics of chemical compounds. In this paper, we introduce the -Nirmala index of a graph. Furthermore we compute this index for benzenoid systems and polycyclic aromatic hydrocarbons. We also establish some other well known graphical indices directly as special case of this index for some special values of a and b, in particular Nirmala index and mean Sombor index.
