“…In our investigations of the optical absorption spectrum of the solvated electron (1)(2)(3)(4)(5)(6) in polar liquids we have, over the past four years, focussed much of our attention on the important question of whether., and to what extent, short-range interactions may be a dominant factor, along with the bulk solvent properties, in determining.the optical properties of the solvated electron. We have approached this question with three different types of experiments: (a) a broad survey of the spectrum of esol in different classes of compounds (3)(4)(5)(6) with a view to determining whether the spectral grouping (3,7) of these absorptions showed any marked dependence upon class of compouhd;…”
