This paper deals with the evaluation of the basis of the mathematical model of interaction of electrochemically activated water solutions (catholyte/anolyte), obtained in the diaphragm electrolysis cell, with water and sodium chloride and the basic physical-chemical processes underlying the electrolysis of water as well. In order to provide additional data about the distribution of H2O molecules according to the energies of hydrogen bonds in the electrochemically activated water solutions of the catholyte and the anolyte, the non-equilibrium energy spectrum 72 European Reviews of Chemical Research, 2015, Vol.(4), Is. 2 (NES) and differential non-equilibrium energy spectrum (DNES) of the anolyte and the catholyte were measured as a result of which were established the basis for evaluation of the mathematical model explaining the behavior of the anolyte and the catholyte regarding the distribution of H2O molecules to the energies of hydrogen bonds. The local maximum for catholyte in the NESspectrum was at -0,1285 eV, for anolyte – at -0,1227 eV and for the control sample of deionized water – at -0,1245 eV. The calculations of ∆EH...O for catholyte with using the DNES method compiles (-0,004±0,0011 eV) and for anolyte (+1,8±0,0011 eV). The average energy of hydrogen bonds between Н2О molecules was measured by the DNES method to be compiled at - 0,1067±0,0011 eV.
