“…However, this model leads to a constant decrease of the IP with n −1/3 . 19 in order to clarify the confusion in the literature concerning the bulk PET values. Therefore the authors proposed for n ജ 6, based on the ideas of Jortner, 10 structures according to the two-center model.…”

In a continuous neat supersonic expansion ammonia clusters are generated and doped with sodium atoms in a pickup cell. Thus clusters of the form Na(NH(3))(n) are produced that are photoionized by a tunable dye laser system. The ions are mass analyzed in a reflectron time-of-flight mass spectrometer, and the wavelength dependent ion signals serve for the determination of the ionization potentials (IP) of the different clusters in the size range 10< or =n< or =1500. Aside from a plateau for 10< or =n< or =17 and smaller steps at n=24, 35, and 59 on the average a continuous decrease of the IP with cluster size is observed. The IPs in this size range are linear with (n+1)(-13) and extrapolate to IP(n=infinity)=1.66+/-0.01 eV. The slope is consistent with a dielectric continuum model of the solvated electron and the dielectric constant of the solid. The extrapolated IPs are compared with results obtained for negative ammonia cluster ions and metallic solutions in liquid ammonia. Differences are explained by the presence of counterions and their various distances from the solvated electron.

“…The free energy AGe differs from the threshold energy Et because of the contribution from the surface potential x and possibly a systematic shift inherent to the extrapolation method and theory [7] (1), one computes "G = 3.58 eV. Another limit can be set on the value of AG by using the gas-phase first ionization energy of water I = 12.61 eV …”

“…The extrapolation strictly holds for measurements of the kinetic energy corresponding to the velocity component of electrons in the gas phase which is normal to the emitting liquid surface. Brodsky has argued [9,10] that experimental EDC's of liquids obtained by the retarding potential method essentially satisfy the foregoing conditions. Table 1 is possible only for ethylene alycol on the basis of the EDC's in [11,12] Table I.…”

“…3), can be approximated [5,9,10] by the functional dependence (E -Et)n on photon energy, where * Et is the threshold energy and the exponent n is taken to be 3, 5/2 or 2 depending on the range of E above Et. The value n = 3 holds very near the threshold energy Et whereas n = 5/2 and n = 2 apply successively at higher photon energies.…”
