An analogy with a cart on a roller coaster partially explains the shuttling motion of macrocycles in peptide rotaxanes. Just above the barrier to shuttling, the macrocycle statistically populates the “track” rather than the low‐energy “stations” (see the potential energy curve). The dynamics of the movement is described in terms of a simplified one‐dimensional model based on the solution of the relevant quantum‐mechanical equation. x =position.
