Geometrical structure of solvated electrons in γ-irradiated 3-methylpentane glass at 77 K from an analysis of the modulation of the electron spin echo decay envelope

Deuterium modulation of the electron spin echo decay envelope from trapped electrons in γ-irradiated 3-methylpentane-d14 glass at 77 K has been analyzed to give a solvation structure characterized by 18–21 equivalent nearest neighbor deuterons to the electron at a distance of 3.0–3.2 Å and with an isotropic coupling constant of essentially zero. From the structure of 3-methylpentane it is suggested that there are six to seven first solvation shell molecules around the electron.
