Investigation of the nature of light scattering by water

Capabilities of light scattering effects for researches of structural properties of water are analysed. It is shown that measuring of indicatries of light scattering by water for different incident radiation intensities make it possible to determine degree of water polydispersity, along with dimensions and concentration of scattering centres. We provide information on how the ions contained or gases dissolved in the water, the temperature, structural phase transitions, mechanical influence, purification efficiency and the sources of water affect the characteristics of the scattering centres, thus facilitating some important conclusions about the structure of water clusters.
