Query: Specific Heats Cp, Cv, Cconf. and energy landscapes of glassforming
  liquids   In pursuit of understanding of the paradoxical success of the Adam-Gibbs
equation in both experiment and computer simulation studies, we examine the
relation between liquid behavior at constant pressure and constant volume and
compare the inherent structures excitation profiles for the two cases. This
allows us to extend qualitatively the recent correlation of kinetic and
thermodynamic measures of fragility to constant volume systems. The decreased
fragility at constant volume is understood in terms of the relation Cp >Cc(cp)
> Cc(cv) > Cv. In the process, we find a parallel between the range of volumes,
relative to the total excess volume, that are explored in the first few orders
of magnitude of relaxation time increase, and the range of amorphous state
inherent structure energies, relative to the total range, that are explored in
ergodic computer simulations, which also cover only this limited range of
relaxation time change. The question of whether or not fragile behavior is
determined in the configurational or vibrational manifold of states is left
unanswered in this work. However, the approximate proportionality of the
configurational and total excess entropies that is needed to interpret the
success of the Adam Gibbs equation (which has been questioned by other authors)
is confirmed within the needed limits, using data from three different types of
investigation: experiments (on Se), simulation (of water in the SPC-E model),
and analytical models of both defect crystals and configurationally excited
liquids. Some consequences of the abrupt increases in vibrational heat capacity
at Tg implied by this proportionality, are discussed.
