Ion-induced dipole H−n clusters
@article{Sapse1979IoninducedDH, title={Ion-induced dipole H−n clusters}, author={Anne Marie Sapse and M. T. Rayez-Meaume and Jean Claude Rayez and L. J. Massa}, journal={Nature}, year={1979}, volume={278}, pages={332-333} }
THERE has long been an interest in the study of ion-induced dipole clusters of the type H+n (n, odd integer). These positive clusters may be present in gaseous nebulae1,2, and Clampitt and Gowland3 have discovered in mass spectrometer experiments such H+n ions for 3≤n(odd)≤99. The ions are very weakly bound because of the nature of the ion-induced dipole forces involved, and thus must be produced at low temperatures. In these experiments a layer of hydrogen gas is deposited on a metal surface…

By recalculating the energetics of the ion induced dipole clusters using density function theory (DFT) B3LYP method calculations, it is proved that in general they are not true minima because not all the resulting frequencies correspond to real values.

A flexible and polarizable interatomic potential has been developed to model hydrogen clusters interacting with one hydrogen anion, in a broad range of sizes n = 1-54, and it is found that strong finite size effects are also found between magic numbers, associated with more prominent vibrational delocalization.

DMC simulations were performed on anionic hydrogen clusters and their deuterated analogs using a polarizable all-atom potential energy surface (PES) and it was found that the "more quantum" H2 molecules prefer to reside farther from the central H- ion than the D2 molecules.
