Abstract: In chemical graph theory, many topological indices of the hexagonal chains, for instance, the energy, Wiener and Kirchhoff indices, and numbers of Kekulé structures and spanning trees, and so on, have been studied extensively. We enumerate spanning trees with a Kekulé structure in the linear hexagonal chains on the plane, cylinder and Möbius strip, respectively.
