  abstract = {Dielectric measurements were obtained on poly(propylene glycol) (molecular
	weight: 4000 Da) at pressures in excess of 1.2 GPa. The segmental
	(alpha process) and normal-mode (alpha' process) relaxations exhibited
	different pressure sensitivities of their relaxation strengths,
	as well as their relaxation times. Such results are contrary to
	previous reports, and (at least for the dielectric strength) can
	be ascribed to the capacity for intermolecular hydrogen-bond formation
	in this material. With equation-of-state measurements, the relative
	contributions of volume and thermal energy to the alpha-relaxation
	times were quantified. Similar to other H-bonded liquids, temperature
	is the more dominant control variable, although the effect of volume
	is not negligible.},
