In the present manuscript we review the chemistry of aqueous electrons, as studied by Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. FT-ICR studies of the (H 2 O) n − reactions have the advantage that compared with bulk solut

An H/D-exchange reaction involving the methyl group of acetonitrile is observed in the small anionic water cluster OH-(CD3CN)(H2O)2. In this cluster, a randomization of H and D atoms takes place, and in subsequent collisions with CD3CN, the potential
