Abstract:

Interpretation of optical excitation energies of solvated electrons in liquids and solids requires consideration of the solvent structure and the polarizabilities of the solvating groups. The importance of solvent structure is illustrated through the use of the Kirkwood correlation factor gk, which indicates the extent to which molecules align themselves with their neighbors to create short-range order. Values of Emax, the energy at the absorption maximum, for e-solv in water, alcohols, ethers, ammonia, and amines measured over wide ranges of temperature and pressure correlate approximately with epsilondgK cubedalpha sub p where epsilon and d are the dielectric constant and density of the liquid, respectively, and alpha sub p is the polarizability of the polar group in the molecule. A more detailed treatment would consider the anisotropy of alpha sub p. Author
