Abstract

The conversion of ice to water is a process riddled with enigmas. We tested the possibility that ice does not transition directly to water, but first to an intermediate phase that has been recently identified. That intermediate is the interfacial \“exclusion zone” phase. The phase is characterized by strong absorption of light at 270 nm. We found indeed that as ice melts, a transient 270-nm absorption phase occurs, which eventually gives way to bulk water containing no such absorption peak. Hence, the results support the hypothesis. Keywords: exclusion zone, EZ, ice, UV-Vis spectroscopy, melting.
