摘要：

Cesium atoms solvated with polar solvents, Cs(H2O)n, Cs(NH3)n and Cs(CH3CN)n, are studied by one-photon ionization and time-of-flight mass spectroscopy. The ionization potentials of Cs(H2O)n and Cs(CH3CN)n are found to be constant for n greater-than-or-equal-to 4 (3.1 eV) and n greater-than-or-equal-to 12 (2.4 eV), respectively, while that for Cs(NH3), decreases monotonically with increasing n to a limit of 1.4 eV, which coincides with the bulk value. Enhanced stability at n = 20 is also observed for the Cs(H2O)n clusters. These features are discussed in connection with the stability of the excess electrons in these solvents.
