摘要

The spontaneous formation of a skin layer of distilled water, up to 3 mm thick, with new properties over ~4 h has been discovered. Deformation of the Raman OH band due to the contribution of the ice component (~3200 cm–1), a decrease in the elastic scattering coefficient and its fluctuations, and a ~20% increase in the height of the meniscus in capillaries have been detected. The recovery of the layer after enrichment with air due to mixing indicates the stability of the formation of ice-like structures. The filling of the ice-like structures with H2O monomers, which form hydrogen bonds with SiO2 molecules of the capillary walls, increases their wettability and, consequently, the height of the meniscus.
