Low-temperature sputtering of frozen aqueous solutions of metal salts, of hydrated crystalline transition-metal salts, of frosted metal surfaces, and of frosted metal salts with kiloelectronovolt energy rare gas atoms or ions produces copious amounts of cluster ions, among which M(1+)(H2O)n and/or M(1+)OH(H2O)n frequently dominate.Variable-energy collision-induced dissociation of these ions in a triple quadrupole mass spectrometer yields the successive gas-phase solvation energies.Several known hydration and bond energies have been reproduced, and the first and secondhydration energies of the Cu(1+) ion have been determined as 35 +/- 3 and 39 +/- 3 kcal/mol, respectively.It is concluded that gaseous Cu(1+) prefers dicoordination.
