The enthalpy relaxation of the pentose isomers (d-xylose,d-ribose,l-arabinose, andd-arabinose) was investigated in terms of the Tool–Narayanaswamy–Moynihan and Adam–Gibbs–Vogel models using differential scanning calorimetry. Single set of parameters for each model was obtained from the multicurve-fitting procedure. The differences between the glass transition and relaxation parameters were discussed in terms of isomeric effect. The cooperativity determined from curve-fitting results was further compared to those obtained via Donth’s formula.
