  • ARecently, Ghorbani et. al. introduced the eccentric versions of first and second Zagreb indices called third and fourth Zagreb indices defined as M3 GG = ∑uv∈EGG ℇ(uℇ(u + ℇ vv) and M4 GG = ∑v∈VGGℇvv2, respectively, where ℇvv is the eccentricity of the vertex v. In this paper, we compute the closed formula for third Zagreb index of Polycyclic Aromatic Hydrocarbons PAHkPAHk.
