High-frequency dielectric permittivity of water and its components

The values of electron polarizability of water molecules in a medium and the values of water deformational dielectric permittivity (ɛ∞) and its components (electron (nv), nuclear (Δnnuc), and vibrational intermolecular (Δninter)) are calculated. It is shown that T → Tcr, ɛ∞inter and Δninter approach zero, while Δnnuc in the range (Tmelt − Tcr) has a maximum located at around T = 0.785Tcr.
