International Journal of Quantum Chemistry, 2018 AbstractLet Hn be a linear crossed hexagonal chain with n crossed hexagonals. In this article, we find that the Laplacian (resp. normalized Laplacian) spectrum of Hn consists of the eigenvalues of a symmetric tridiagonal matrix of order 2n + 1 and a diagonal matrix of order 2n + 1.

International Journal of Quantum Chemistry, 2019 AbstractLet Ln denote the linear hexagonal chain containing n hexagons. Then identifying the opposite lateral edges of Ln in ordered way yields TUHC[2n, 2], the zigzag polyhex nanotube, whereas identifying those of Ln in reversed way yields Mn, the hexagonal Möbius chain.
