Photoelectron spectra of solvated electrons in bulk water, methanol, and ethanol

Photoelectron spectra of solvated electrons in bulk liquids were obtained at energy-resolution of 60 meV using a linear time-of-flight photoelectron spectrometer and a 100 kHz ultraviolet femtosecond laser. Solvated electrons in H2O, D2O, methanol, and ethanol were generated by 226 nm excitation of the charge-transfer-to-solvent bands of I in 0.1 M NaI solutions, and the photoelectron spectra were measured using 260 nm pulses with a time delay of 2 ns. The electron binding energies and band shapes are discussed. (C) 2012 Elsevier B. V. All rights reserved.
