ZEKE-PFI spectroscopy of the Al–(H2O) and Al–(D2O) complexes

Infrared spectroscopy of V+(H2O) and V+(D2O) complexes: Solvent deformation and an incipient reaction

“…Gas phase ion chemistry explores model metal cationwater complexes, 1-5 but their spectroscopy is limited. [6][7][8][9][10][11] Lisy and co-workers studied alkali cation-water complexes in the O-H stretch region with infrared photodissociation ͑IRPD͒ spectroscopy. 11 Our group has recently applied IRPD to transition metal ion complexes.…”

Microsolvation in V+(H2O)n Clusters Studied with Selected-Ion Infrared Spectroscopy

“…The solvation of metal cations by water underlies many important chemical systems, such as electrochemical reactions, acid–base chemistry, atmospheric aerosols, and the many aqueous biochemical processes that govern life itself. − The molecular details of cation–water interactions have been investigated with many studies of the mass spectrometry of gas-phase ion–molecule complexes − and with corresponding computational studies. − Collision-induced dissociation measurements have determined cation–water binding energies, while computational studies have provided structures, relative energetics, and predicted spectra for complexes with different numbers of water molecules and different charge states. Spectroscopic experiments in either the UV–visible or infrared regions have determined the structures and the coordination numbers of different metal ions interacting with water. − In the present report, we use mass spectrometry and infrared photodissociat...…”

“…The spectroscopy of hydrated metal ions has examined the solvation effect of water on the atomic transitions of metal ions and the polarization effect of metal ions on the structure and bonding in water molecules. Electronic spectroscopy of mass-selected ions examined the atomic transitions in transition-metal cations and those of alkaline-earth-metal cations bound to one or more water molecules. − Among this group, Brucat and co-workers reported the electronic spectra for V + (H 2 O), our group, Fuke and co-workers, and Kleiber and co-workers investigated alkaline-earth cation complexes with water, − ,− and the group of Kleiber and that of Metz studied other transition-metal cation–water complexes. ,− Unfortunately, these electronic spectra of cation–water complexes exhibit sharp vibrational structure only for those species containing a single water molecule. Apparently, predissociation in excited electronic states leads to broad, continuous spectra for multiwater complexes.…”

Structure and spectroscopic aspects of water‐halide ion clusters: A study based on a conjunction of stochastic and quantum chemical methods

“…These red‐shifted peaks, especially the ones formed from ionic‐hydrogen bond (OH···X − ), is a typical signature of these systems as compared to the IR spectroscopy of (H 2 O) n Y + (Y + = alkali metal ion) where the ionic hydrogen bonds are absent. [6, 7, 43–48]…”
