A method is reported for the determination of ionization energies of liquids or solutions by means of photoelectron spectroscopy PES. The method is based on the determination of second derivative of the quantum yield with respect to retarding potential as a function of retarding potential. The resulting spectrum for liquid is compared to gas-phase PES, and the liquid-gas photoionization shift is explained. This is, to our knowledge, the first determination of its kind in liquid-phase ultraviolet PES. A number of applications is foreseen. Author
