Abstract—The main concepts of the new theory of processes with the participation of excess electrons in polar
liquids are considered. The theory takes into account that (1) polar liquids are electrostatically inhomogeneous
(local potentials on molecules are different) and (2) a molecule can accept an electron for a short time to pro-
duce an anion in an unstable state with a certain energy and lifetime. A discrete model of a substance consisting
of molecules with constant dipole moments is used. Excess electrons in a liquid are described by energy distri-
bution density, and the behavior of electrons, by quantum mechanics equations. The experimental data on the
photoionization of water and aqueous solutions of salts and the low threshold energy of photons (~6.5 eV) at
which solvated electrons appear in water are explained. The absorption spectra of water with excess electrons
at the first and subsequent time moments after their photogeneration are reproduced theoretically. The depen-
dence of the photoemission of solvated electrons from potassium–ammonia solutions on the energy of photons
is interpreted. The continuous spectrum of spontaneous radiation of solvated electrons in liquid ammonia and
water is calculated. The optical absorption spectra of solvated electrons in such polar liquids as water and
ammonia are reproduced.
