The vibrational Stark $effect1$ has been used to calculate the frequency shifts observed in the vibrational predissociation spectra of $Cs+(NH3)n;n=5-12$, and $Cs+(CH3OH)m;m=5-12$, ion clusters. The electric field was obtained for each cluster by averaging over 400 Monte Carlo generated configurations. The ligands were approximated by polarizable dipoles and the ion was treated as a point charge. Experimental results will be compared to calculated frequency shifts and ligand effects will also be discussed.
