Possible link between dynamics and thermodynamics
Amorphous and glassy states of molecular and pharmaceutical compounds: general properties

A link between the dynamic behavior and thermodynamic characteristics of glass-forming liquids emerges from what has been described above.

Strong liquids have an Arrhenian dynamic behavior and exhibit a small value of ΔC_p at T_g.

Brittle liquids have a very super-arrhenic dynamic behavior and generally exhibit a large value of ΔC_p at T_g.

For these fragile compounds, the Kauzmann temperature T_K is usually close to the VFT temperature T₀, where the relaxation time extension diverges virtually to infinity. This suggests that configurational rearrangements would be blocked at T_K if the liquid could be cooled to this temperature while...
