Abstract
Vibrational predissociation spectra of mass selected $M^{+}(MeOH)_{N}$ and $M^{+}(EtOH)_{N}$ (where $M= Na^{+},K^{+},Rb^{+})$ have been observed by exciting the C-O stretching mode of the MeOH or the $CH_{3}$ wag of the EtOH in the $9.6 \mu$ region. The solvated ions are produced by combining a thermionic ion source with a supersonic nozzle. Spectra from cluster ions with as many as 25 solvent molecules have been observed. From the spectral dependence on the solvent number surrounding the ion, we have observed the formation of solvation shells. Comparisons will be made to $Cs^{+} (MeOH)_{N}{^{1}}$ and $C_{s}{^{+}} (EtOH)_{N}$.
