Electronic Absorption-Spectra of Size-Selected Hydrated Electron Clusters - (H2O)(N)(-), N=6-50
We report photodestruction spectra for the (H2O)(n)(-) clusters (n=6, 11, 15, 20, 25, 30, 35, 40, and 50) in the range 0.7-1.6 eV. The spectra are observed to strongly redshift and narrow with decreasing cluster size, with a concomitant increase in peak intensity. The maxima occur well below the vertical detachment energies for n>20 and almost exclusively result from excitation of a bound-bound transition.
