Infrared spectroscopy of hydrated sulfate dianions
We report the first infrared spectra of multiply-charged anions in the gas phase. The spectra of SO 4 2 − ∙ ( H 2 O ) n , with n = 3 - 24 , show four main bands assigned to two vibrations of the dianionic core, the water bending mode, and solvent libration. The triply degenerate SO 4 2 − antisymmetr...
