Abstract
Let E(VC5C7 [4p,8]) and EE(VC5C7 [4p,8]) denote the energy and Estrada index of VC5C7 [4p,8] nanotube, where p
denotes the period of this C5C7 nanotube. In this paper some calculations are given by which it is possible to suggest
conjectures about energy and Estrada index of this nanotube. We conjectured E(VC5C7 [4p,8]) = 47.4018 + 47.3(p − 1)
and EE(VC5C7 [4p,8]) = 99.3238 + 99.2(p − 1).
Keywords
VC5C7 [4p,8] nanotube, energy, Estrada index.
