Geometrical H/D isotope effect on hydrogen bonds in charged water clusters

Tachikawa, Masanori*; Shiga, Motoyuki

Isotope effect of hydrogen can sometimes subtlely change the strength of hydrogen bonds. From a detail analysis of positively and negatively charged water clusters by ab initio path integral molecular dynamics, we have found that oxygen-oxygen bonds shortens in positive ions while lengthens in negative ions as a result of deuterization. The former is ascribed to the anharmonicity of the OH bond, the latter is ascribed to the resonance of the O-H-O bond.

The quartet ESR lines observed in X-ray irradiated solid parahydrogen, which have previously been assigned to H, are reinvestigated. We have reassigned the quartet lines to H rather than H. Based on the new assignment, previous data have been reinterpreted as follows. The H ion is composed of the collinearly aligned H core at the center and two H rotors at both ends. The ortho-para conversion of H core of H is completed within the time-scale of hours. H diffuses quantum mechanically by the repetition of H + H H + H reaction, and the diffusion terminates by the reaction with a HD impurity as H + HD HD + H. Finally, we will propose a possible reason why H is produced instead of H in the irradiated solid H.
