Nirmala leap indices of some chemical drugs against Covid-۱۹

In Chemical Graph Theory, several degree-based topological indices were introduced and studied since ۱۹۴۷. Some of these have important applications in chemistry while some only have nice mathematical properties. In this paper, we introduce the Nirmala leap index and modified Nirmala leap index, and their polynomials and compute these indices for some important nanostructures which appeared in nanoscience, especially used as a treatment alternative against Covid-۱۹ in many countries.
