Abstract Curie-Weiss temperature dependence of the dielectric permittivity has been shown to take place in water. A bilinear change at has been reported recently. In this work an effective field statistical theory is developed for polar liquids such as water. A change of elementary dipole moment at describes well its behavior with temperature. It implies a change in dipole moment from a value close to that in ice to another close to that in water vapor. The Lindemann relationship is used to estimate the fractional oscillation of the water molecule from melting temperature T = 0 °C to in terms of the water Debye temperature and basic geometrical parameters.
