title: Energy landscape of a hydrogen-bonded non-degenerate molecular shuttle.
abstract: In rotaxane 1, two co-conformations are populated in CDCl(3) at temperatures between 250 and 330 K. The thermodynamic parameters show strong enthalpy-entropy compensation, and a non-negligible heat capacity difference between the two forms.
