  The aging properties of a simple free-energy landscape model for the primary
relaxation in supercooled liquids are investigated. The intermediate scattering
function and the rotational correlation functions are calculated for the
generic situation of a quench from a high temperature to below the glass
transition temperature. It is found that the re-equilibration of molecular
orientations takes longer than for translational degrees of freedom. The time
scale for re-equilibration is determined by that of the primary relaxation as
an intrinsic property of the model.
