Specific-heat spectroscopy of glycerol and propylene glycol near the glass transition
Abstract
We have measured the frequency-dependent specific heat of glycerol and propylene glycol near the glass transition. The measurements, covering a frequency range of five decades, probe the linear response of these supercooled liquids to small perturbations from equilibrium. The specific heat of these two liquids contains a contribution which relaxes increasingly slowly as the temperature is lowered. The relaxation time measured by specific-heat spectroscopy has the same temperature dependence as that measured by other techniques. This suggests that a single mechanism is responsible for all of the observed phenomena associated with the glass transition in these materials.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
