[en] Spectral-kinetic properties of solvated electrons (e_s) were investigated in eight trialkyl phosphates (TAP) by nanosecond pulse radiolysis. It was found that the main reaction determining the radiation-chemical behavior of e_s is their dissociative attachment of TAP molecules in all of the solvents studied. The parameters of optical absorption bands of e_s were measured; the form of spectral curves was analyzed. The results are discussed in terms of a modern view of dissociative e_s attachment reactions and the role of molecular structure in the determination of the localized state of an excess electron

[en] Investigations on the electrolytic generation of hydrated electron in oxygenated as well as oxygen-free solutions at different pH were undertaken. Since sup(-e)aq is known to react rapidly with O₂ yielding the transient O₂^- ion, the latter was looked for through its interaction with phosphite ions resulting in their oxidation near the cathode. It appears from the results that in electrolytic processes, the primary electron (esup(-)sub(cathode)) probably reacts directly with reactive solutes like oxygen, bypassing the hydration step. Data obtained in oxygen-free solutions, however, support the possible formation of hydrated electron at least in alkaline solutions. (author)

[en] The correlation between the maximum of the optical absorption spectrum of the solvated electron, E/sub max/, and the function epsilon dg³α/sub p/ is reexamined. A new correlation is presented in which E/sub max/ is related to the classical semicontinuum charge--solvent interaction energy, U, calculated by assuming that the electron cavity radius is defined by the functional group of the solvent molecule. This treatment is consistent with current theoretical models for electrons solvated by simple molecules and the correlation holds well for a variety of solvents over wide ranges of temperature and pressure

[en] The absorption spectrum of electrons solvated in polar solvents is interpreted in terms of a rectangular potential well with spherical symmetry. The depth and radius of the well are calculated for several solvents and some of their mixtures. The results are realistic in terms of a simple molecular model with a single solvation shell and without significant long-range interactions

[en] We try to review the principal questions which have remained unanswered up to now on the dynamics of electron hydration. We also report controversies on the interpretation of the recent femtosecond laser photolysis experiments, and put forward some new hypotheses concerning the formation of the incompletely relaxed electron. 27 refs
