The spectral regions studied include the solvent v(C≡N) fundamental and several anion internal modes. The silver ion solvation number in the infinite dilution limit is 3 in both systems. This number falls when the salt concentration is increased because of the ionic pairing, which is slightly more intense for silver perchlorate solutions, with a calculated spectroscopic association constant 0.23 ±0.08 kg-mol-1. For silver triflate solutions, the spectroscopic association constant is 0.17±0.05 kg-mol-1. In both cases, the ionic pair structure is bidentate and silver ion preserves two molecules of acrylonitrile in its first solvation shell.
