\(\renewcommand\AA{\unicode{x212B}}\)
This fitting function models the elastic part of the dynamics structure factor of a particle undergoing discrete jumps on N-sites evenly distributed in a circle. The particle can only jump to neighboring sites. This is the most common type of discrete rotational diffusion in a circle.
This function makes up the elastic part of DiffRotDiscreteCircle.
