Abstract

Static permittivity of supercooled water can be calculated from measurements on supercooled ethanol-water mixtures, and suitable extrapolations to zero ethanol concentration. The results support the idea of a continuity of states between liquid and amorphous solid water if crystallization could be avoided. Variations of extrapolated dielectric constant versus temperature are in good agreement with the Sceats and Rice model (1982) taking into account the distribution of the hydrogen bond angles to explain the physical properties of supercooled water and amorphous ice when crystallization is precluded
