Is NaI soluble in water clusters?
\(\) clusters (solvents being \(\), \(\) or \(\)) have been studied by resonance enhanced two photons ionization, leading to the detection of \(\) clusters. When water is the solvent, large clusters up to n>50 can be observed, whereas for \(\) and \(\) no clusters larger than 10 could be evidenced. Because the first step in the ionization process is the excitation from the ground solvated (\(\)) ion pair state to a covalent excited state, the differences in the cluster size distribution for different solvent may be interpreted as a difference in cluster structures leading to a difference in the charge separation in the ground state.
