hydrated electron

[′hī‚drād·əd i′lek‚trän]
(physical chemistry)
An electron released during ionization of a water molecule by water and surrounded by water molecules oriented so that the electron cannot escape. Also known as aqueous electron.

It can be presumed that the morphological changes are a consequence of radical linkage and hydrated electron ([e.sub.aq.sup.-]) affecting the CTAB aqueous solution in certain path [17].
Aqueous solutions containing isopropanol exposed to [gamma]-irradiation lead to the formation of hydrated electrons ([e.sub.aq.sup.-]) and primary species [H.sub.3][O.sup.+], [H.sub.2], [H.sup.*], O[H.sup.*], and [H.sub.2][O.sub.2] (2) [16].
The most fundamental aqueous anion is the hydrated electron and it represents a benchmark for understanding solvation and electron-water interactions in solution.
Calculations for [Cl.sup.-] and water suggest that attractive interactions occur between a neutral atom and a hydrated electron; (81) a similar attraction is anticipated between an I atom and a hydrated electron.
