Hydrogen bonding arrangement of ice II observed in interfacial water attached on hydrophobic and hydrophilic surfaces

Interfacial water dielectric permittivity and electric field profiles were probed and compared. Relative permittivity values between 3 and 4 were measured on both hydrophobic and hydrophilic substrates. Since ice has crystal structures responsible for many of the liquid water properties, Raman spectral lines of ice II were compared to the intramolecular vibrational spectrum of the interfacial air/water region. The coincidence of their spectral lines suggests that the interfacial air/water arrangement is similar to ice II and is induced by the interfacial electric field.
