Two potentials, constant potential and low variable potential (with amplitude of 10 mV) are applied simultaneously in these systems to the metal-solution interface. The aim of the present work is: investigation of the adsorption processes in electrochemical systems by radio-spectroscopic method. The adsorption processes of the organic molecules are of great importance for creation of optochemotronic sensors, for electrochemiluminescence and various other processes. The analytical expressions for coordinates and rate of particles in such system are received. Moreover, expressions for vector-potential of the electromagnetic radiation of the system, which is connected with this motion, are also considered. The main outcome is existence of nonlinear, quadratic dependence between the signal of the electromagnetic radiation of the radio-wave range U and amplitude of a variable potential E, which is applied to the interface. The same dependence exist in electrochemical systems, where there is no current. Obtained theoretical results are used for the analysis of the experimental data, which was received for adsorption-desorption of aliphatic alcohols. Although there is no charge transfer between the alcohol molecules and electrode during the adsorption, quadratic dependence between U and E is investigated for all peaks on desorption SHS(second harmonic signal) - curves of butanol-1, butanol-2, hexanol, pentanol and isoamyl molecules on mercury electrode. For different concentrations of alcohols, different frequencies and values of the amplitude of variable potential were applied. Experimental results confirm the accuracy of proposed theoretical model.enAdsorptionradio-spectroscopycharge transferGreen functionადსორბციარადიო-სპექტროსკოპიამუხტის გადატანაგრინის ფუნქციაtext::journal::journal article
