Glass transition dynamics and boiling temperatures of molecular liquids and their isomers
Article Abstract:
A research is done to determine the correlation between a dynamic and a thermodynamic temperature, glass transition and boiling point for different glass-forming liquids, particularly, monohydroxy alcohols. It is observed that glass transition and boiling point demonstrate inverse correlation within an isomeric series and that the two main factors of the dynamics, fragility and stretching exponent are identical within isomers of moderately different glass transitions.

Diluent effects on the Debye-type dielectric relaxation in viscous monohydroxy alcohols
Article Abstract:
Studies on glass-forming H-bonded liquids provide increasing evidence that the Debye-type relaxation of liquid monohydroxy alcohols does not reflect the structural relaxation dynamics associated with the viscous flow and the glass transition. The behavior of the Debye relaxation upon relaxation is expected to differ from that of real alpha-processes.

Debye type dielectric relaxation and the glass transition of alcohols
Article Abstract:
Many hydrogen-bonded liquids, especially glass-forming cases, display a dielectric relaxation behavior that differs qualitatively from that of the other simple liquids. The prominent dielectric signal with Debye character does not coincide with structural relaxation.
