Abstract
Hydration shells around Rb+ and Cs+ are not symmetric; the cation and the 1st-shell water mass center are separated by ∼0.4 Å, and this is supported by agreement between the theoretical and experimental EXAFS spectrum.

Abstract
Infrared photodissociation (IRPD) spectra of M(+)(H2O)nAr (M = Rb, Cs; n = 3-5) with simultaneous monitoring of [Ar] and [Ar+H2O] fragmentation channels are reported. The comparison between the spectral features in the two channels and corresponding energy analysis provide spectral assignments of the stable structural conformers and insight into the competition between ion-water electrostatic and water-water hydrogen bonding interactions. Results show that as the level of hydration increases, the water-water interaction exhibits the tendency to dominate over the ion-water interaction. Cyclic water tetramer and water pentamer substructures appear in Cs(+)(H2O)4Ar and Cs(+)(H2O)5Ar systems, respectively. However, cyclic water tetramer and pentamer structures were not observed for Rb(+)(H2O)4Ar and Rb(+)(H2O)5Ar systems, respectively, due to the stronger influence of the rubidium ion-water electrostatic interaction. The energy analysis, including the available internal energy and the IR photon energy, helped provide an experimental estimate of water binding energies.

Abstract
A study of the solvation of HgCl(2) including ab initio aggregates of up to 24 water molecules and the results of extensive Monte Carlo simulations for the liquid phase using MP2-derived interaction potentials is presented. The interaction potentials are flexible, polarizable, and include non-additive effects. We conclude that a cluster description of the solvation mechanism is limited when compared to the condensed phase. The molecular image derived from the MC simulations is peculiar. It resembles that of a hydrophobic solute, which explains the rather easy passage of this neutral molecule through the cell membrane; however, it also shows an intermittent binding of one, two, or three water molecules to HgCl(2) in the fashion of a hydrophilic solute.

Abstract
![]()
The hydration of the alkali metal ions in aqueous solution
has been studied by large angle X-ray scattering (LAXS) and double
difference infrared spectroscopy (DDIR). The structures of the dimethyl
sulfoxide solvated alkali metal ions in solution have been determined
to support the studies in aqueous solution. The results of the LAXS
and DDIR measurements show that the sodium, potassium, rubidium and
cesium ions all are weakly hydrated with only a single shell of water
molecules. The smaller lithium ion is more strongly hydrated, most
probably with a second hydration shell present. The influence of the
rubidium and cesium ions on the water structure was found to be very
weak, and it was not possible to quantify this effect in a reliable
way due to insufficient separation of the O–D stretching bands
of partially deuterated water bound to these metal ions and the O–D
stretching bands of the bulk water. Aqueous solutions of sodium, potassium
and cesium iodide and cesium and lithium hydroxide have been studied
by LAXS and M–O bond distances have been determined fairly
accurately except for lithium. However, the number of water molecules
binding to the alkali metal ions is very difficult to determine from
the LAXS measurements as the number of distances and the temperature
factor are strongly correlated. A thorough analysis of M–O
bond distances in solid alkali metal compounds with ligands binding
through oxygen has been made from available structure databases. There
is relatively strong correlation between M–O bond distances
and coordination numbers also for the alkali metal ions even though
the M–O interactions are weak and the number of complexes of
potassium, rubidium and cesium with well-defined coordination geometry
is very small. The mean M–O bond distance in the hydrated sodium,
potassium, rubidium and cesium ions in aqueous solution have been
determined to be 2.43(2), 2.81(1), 2.98(1) and 3.07(1) Å, which
corresponds to six-, seven-, eight- and eight-coordination. These
coordination numbers are supported by the linear relationship of the
hydration enthalpies and the M–O bond distances. This correlation
indicates that the hydrated lithium ion is four-coordinate in aqueous
solution. New ionic radii are proposed for four- and six-coordinate
lithium(I), 0.60 and 0.79 Å, respectively, as well as for five-
and six-coordinate sodium(I), 1.02 and 1.07 Å, respectively.
The ionic radii for six- and seven-coordinate K+, 1.38
and 1.46 Å, respectively, and eight-coordinate Rb+ and Cs+, 1.64 and 1.73 Å, respectively, are confirmed
from previous studies. The M–O bond distances in dimethyl sulfoxide
solvated sodium, potassium, rubidium and cesium ions in solution are
very similar to those observed in aqueous solution. The hydration of alkali metal ions has been studied by large angle
X-ray scattering, LAXS, and double difference infrared spectroscopy.
The obtained M−O bond distances from LAXS have been compared
to relevant crystal structures, conclusions about hydration numbers
in aqueous solution have been made, and new ionic radii have been
proposed. Hydration numbers of six, seven, eight and eight are proposed
for the sodium, potassium, rubidium and cesium ions in aqueous solution.
