Abstract
Families of model 'rugged landscape' potential energy functions were studied to establish the relationship between thermodynamic and kinetic behaviors of glassforming substances. The family of 'rugged' one-dimensional potential energy functions were composed piecewise out of single basin units. Pairs of functions producing identical thermodynamic properties and having different dynamics-controlling topographies were identified, implying a logical disconnection between the two aspects. A need for a principle, not purely mathematical in nature, to explain the empirical connection between thermodynamic and kinetic properties of supercooled liquids was also discussed.
