Description
Summary:In this paper we derive a formula to calculate the amount of free water molecules in solution. Physical values in this formula may be obtained by analyzing the spectra of aqueous solutions in the terahertz frequency range. Formula is derived on the basis of considering water polarization process in electric field. It is shown that without processes of shielding the electric field in the water calculations lead to very high estimation of a share of free water molecule.
