Molecular chains interacting by Lennard-Jones and Coulomb forces

We study equations for the mechanical movement of chains of identical particles in the plane interacting with their nearest-neighbors by bond stretching and by van der Waals and Coulomb forces. We find colinear and circular equilibria as minimizers of the energy potential for chains with Neumann and periodic boundary conditions. We prove global bifurcation of periodic solutions from these equilibria applying the global Rabinowitz alternative in subspaces of symmetric functions. These results are complemented with numeric computations for ranges of parameters that include carbon atoms among other molecules.
