Abstract: | Density Functional Theory (DFT) and direct ab initio molecular dynamics (MD) calculations were applied to the hydrogen molecule trapped in a water cluster composed of 12 water molecules (H2O)12. The static DFT calculation showed that the H2 molecule is trapped in the center of mass of (H2O)12. The vibrational frequency of the H–H stretching mode of the H2 molecule trapped in the water cluster was blueshifted from that in vacuo. On the other hand, the vibrational frequency of H2 in water‐hydrogen 1:1 complex (H2O–H2) was redshifted. A direct ab initio MD calculation of H2(H2O)12 at 50 K indicated that the H2 molecule is rotated freely around the center of mass of the water cluster. The origin of the spectral shift of H2 in water ice is discussed on the basis of the theoretical results. © 2004 Wiley Periodicals, Inc. Int J Quantum Chem, 2005 |
