Potential energy in units of of two dipolar dumbbells with center-to-center separation in various orientations with respect to each other and to the center-to-center vector .
Interaction energy per particle of two parallel idealized chains of 20 head-to-tail dipoles, shifted with respect to each other by along their axes, as a function of the separation of the chain axes. The four curves correspond to different dumbbell extensions, . Each curve has been scaled in length by the equilibrium pair separation and in energy by the minimum pair energy [see Eq. (2)] for the relevant value of . The thick line corresponds to the adopted in the present work.
