Mass-selected photodetachment-photoelectron spectroscopy of negatively charged molecular systems of the form HxSy•(H2O)n (n = 0-3) was performed. By this means electron affinities, vertical detachment energies, vibrational frequencies and electronic states were investigated. In particular, transition states of proton-transfer reactions in the model systems HS•(H2S) and DS•(D2S), but also in the larger microsolvated systems (HS•(H2S)•(H2O) and HS•(H2S)2) were in the scope of this work. The systems H2S2, H2S2•(H2O)n (n = 0 - 3) and HS2, which play an important role in various industrial processes, corrosive processes and in atmospheric chemistry, were also studied. The interpretation of the observed photodetachment-photoelectron spectra was supported by anionic and neutral structure calculations and by calculated vertical detachment energies of the corresponding systems.
