Hueckel pi-MO eigenvalues of benzene: epsilon_k = alpha + 2 beta cos(2 pi k / 6) (molecules)

Chemistry application of L1 quantum-hilbert-space and angular-momentum-quantum. Hueckel's 1931 pi-electron theory replaces the full molecular Hamiltonian with a simple graph-theoretic adjacency matrix in the basis of carbon 2 p_z atomic…
