FIG. 1.

Heat capacities measured as a function of temperature for , , and . The filled black squares are the measured values. The heat capacities are plotted relative to the classical value , where and is the Boltzmann constant. The open blue circles are a fit obtained using a three-state model using (see text). The solid blue lines show heat capacities obtained from the fit with . The lines at the bottom of each plot show the relative abundances of the low energy structure (green), high energy structure (purple), and liquid (red) as a function of temperature (using the scale on the right hand axes).

FIG. 2.

Heat capacities recorded for after annealing to 523 and 773 K (filled black squares). The heat capacities are plotted in units of , where and is the Boltzmann constant. The heat capacities for unannealed are included for comparison. The blue lines are fits to the experimental date values using two- and three-state models with (see text).
