A new broadband dielectric spectroscopy technique, operating from some Hz up to the microwave frequency region, has been used to study the collective dynamical aspects of some simple molecular liquids approaching their glass transition temperature. Accessing to the relaxational dynamics of metatoluidine (CH[sub 3]C[sub 6]H[sub 4]NH[sub 2]) on a mesoscopic timescale, a very high value of fragility has been obtained for this liquid in the classification scheme recently refined by Angell. © 2000 American Institute of Physics.

    The molecular dynamics of the aromatic core as well as the hydrocarbon side chains have been studied in a new kind of glass-forming discotic liquid crystal, based on a triphenylene core. It serves as a model compound in which only a limited number of degrees of freedom is activated at the glass...

    It is frequently assumed that in the limit of vanishing cooling rate, the glass transition phenomenon becomes a thermodynamic transition at a temperature TK. However, with any finite cooling rate, the system falls out of equilibrium at temperatures near Tg(>TK), implying that the very existence...

    Supercooled liquids exhibit a pronounced slowdown of their dynamics on cooling without showing any obvious structural or thermodynamic changes. Several theories relate this slowdown to increasing spatial correlations. However, no sign of this is seen in standard static correlation functions,...
