Proton Magnetic Resonance Evidence of a Liquid Phase in Polycrystalline Ice

Nature Physical Science volume 230, pages 91–92 (1971)Cite this article

Abstract

PROTON magnetic resonance (PMR) spectra1–3 of ice between −20° C and the melting point include a narrow component which suggests that a small proportion2 of the protons (0.2% to 0.4% at −12° C) are in a liquid-like state. Possible explanations are a quasi-liquid surface film, freezing point depression due to surface free energy effects at grain corners or presence of impurities and interstitial non-hydrogen bonded water molecules.
