Configurational entropy Adam-Gibbs relation

C. Adam-Gibbs Relation Between the Configurational Entropy Sc and Relaxation in Glass-Forming Liquids... [Pg.125]

In liquids, one of the most celebrated equations that connects the microscopic dynamics of molecules with thermodynamics is the Adam-Gibbs relation. This relates the translational diffiisivity of the system to configurational entropy as follows ... [Pg.157]

Figure 10.3. Correlations between diffusion coefficient, configurational entropy, and tetrahedral order parameter (/h). Note that the left side of the y-axis represents the logarithm of diffusivity and the right side of ffie y-axis represents (th). The straight line fitting of the data validates the Adam-Gibbs relation between entropy and the diffusion coefficient, as discussed in the text The dashed line shows the correlation between (th) and configurational entropy.
