Nano-cluster model of formation of liquid water

A new cluster model of formation of liquid water is proposed. According to this model the condensation of water vapor is preceded by the formation of polymolecular water nano-clusters (clusters of «hidden» phase or quatarons), which, according to the classical nucleation theory, should not be. Condensation of different in their structure and size quatarons leads to the formation of various condensed phases. The main structure-forming units for real water are hollow quatarons dodecahedronor truncated octahedron-shaped containing 20÷24 molecules of water or dense quatarons of icosahedral shape, containing 13 water molecules. At the same time, water with density of ≈ 1 g/cm3, corresponding to real water, can be formed by merging of clusters containing approximately 560 molecules. This dual way of formation of liquid water suggests that ordinary water is, at least at the stage of formation, a mixture of two phases ("structured" in the first case and unstructured - in the second one). This conclusion should not be understood as the repetition of the known two-structure model of water, considering water as an additive mixture of ice-like structure and unbound single water molecules, since in this case there are no fields with very different densities and boundaries of the division. Despite the various possibilities of formation of liquid water its consequent "life" and the properties are determined mainly by the establishing hydrogen bonds between water molecules. Accordingly, the proposed model does not allow the existence in water of longlived memory and structures in the form of polymer matrices.
