    • 14 of this paper states that the cited values (Formula presented) and (Formula presented) are maximum values and changes in the noncritical background would yield smaller values that lie within the error bounds. Thus (Formula presented) and (Formula presented) seem most likely.PLRAAN

(1) and (2) for frequencies up to (Formula presented) and (Formula presented) for the Kent State and MIT calorimeters, respectively. As the frequency is decreased from these values, the dominant thermal relaxation is that for heat flow from the sample plus cell to the bath, here the sample plus cell system acts like a single “lump.” The breakdown of the one-lump thermal model arises from the onset of thermal gradients at high enough frequencies where either the cell or sample or both can no longer follow the thermal oscillations. For the MIT cell design, two distinct thermal paths exist linking the thermometer and heater, one through the LC sample and another along the silver skin of the cell. The behavior of (Formula presented) and φ can be modeled qualitatively by a parallel-path thermal model where heat flow through both paths are described separately by a one-lump model then combined as two parallel resistors. This approach can in principle justify the empirical use of a negative (Formula presented) value for correcting data at 31.75 and 62.5 mHz.PHRVAO

    • A first-order transition with a tiny step in (Formula presented) and a qualitatively small latent heat was observed on cooling at (Formula presented) at MIT and at (Formula presented) at Kent State. This is presumably a transition between (Formula presented) and (Formula presented) which is the stable form at room temperature. Note that (Formula presented) melts at (Formula presented) so this transition is monotropic
