✦ Synopsis

Cesium atoms solvated with polar solvents, Cs(H,O)., Cs(NH,), and Cs(CH,CN),, are studied by one-photon ionization and time-of-IX&t mass spectroscopy. The ionization potentials of Cs(H,O), and Cs(CH,CN), are found to be constant for n& (3. I eV) and n 2 I2 (2.4 eV), respectively, while that for Cs( NH3). decreases monotonically with increasing n to a limit of I .4 eV, which coincides with the bulk value. Enhanced stability at n=20 is also observed for the Cs( H,O). clusters. These features are discussed in connection with the stability of the excess electrons in these solvents.

Pseudo-first-order rate constants (k obs ) for the reaction of piperidine with phthalimide vary linearly with the total concentration of piperidine ([Pip] T ) at a constant content of CH 3 CN in H 2 O-CH 3 CN solvents within the CH 3 CN content range 2-80 % (v/v). The change in k obs with the change
