Emission phenomena in electrochemical systems: Investigation of solvated and delocalized electrons in polar media

The principles of using the results of studies of emission phenomena in electrochemical systems for determination of the energy levels of excess (solvated and delocalized) electrons in electrolyte solutions are formulated. The energy characteristics of excess electrons in hexamethylphosphoric triamide have been estimated on the basis of data obtained by the author and literature data (results of photo- and thermoelectron emission measurements and equilibria studies in solutions of solvated electrons). The energy levels of solvated electron and bi-electron, their photoionization energies and solvent reorganization energies have been found. The nature of the absorption spectra is discussed.
