Vibrational Spectroscopy of the Cl-(H2O)n Anionic Clusters, n = 1−5
Abstract
The hydrogen-bonded and free OH stretch modes of Cl - (H 2 O) n ( n = 1−5) have been observed by vibrational predissociation spectroscopy in the 2.6−3.2 μm region. Besides demonstrating that all clusters form strong ionic hydrogen bonds, the spectra provide clear evidence of water−water hydrogen-bonding networks in n = 4 and n = 5, with the broad spectrum of n = 5 resembling that of large neutral water clusters. No water−water hydrogen bonding is seen in n = 2 and n = 3, but these clusters appear to be solvated asymmetrically. While the data suggest that Cl - ion is solvated on the surface of water clusters, there are discrepancies between the observed spectra and ab initio predictions. This disagreement may stem from either zero-point motion or high cluster temperature, which tend to disrupt hydrogen bonding among the waters.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
