Hydrogen bond relaxation dynamics and the associated symmetric, volumetric, vibronic, and phase transitional anomalies of frozen H2O under compression

  author={Chang Q Sun and Xi Zhang and Weitao Zheng},
  journal={arXiv: Other Condensed Matter},
Coulomb repulsion between the unevenly-bounded bonding "-" and nonbonding ":" electron pairs in the "O2- : H+/p-O2-" hydrogen-bond is found to originate the anomalies of low-compressibility, phonon relaxation dynamics, proton symmetrization in the hydrogen-bond, and the change of the critical temperature for the VIII-VII phase transition of ice under compression. The resultant force of the compression, the repulsion, and the uneven binding strength of the electron pairs make the softer… 


Tunnelling and zero-point motion in high-pressure ice
The microscopic structure of ice poses a long-standing challenge to theory. Because of their low mass, the protons in the hydrogen bonds that define the structures of crystalline ice are susceptible
The nature of the hydrated excess proton in water
Explanations for the anomalously high mobility of protons in liquid water began with Grotthuss's idea, of ‘structural diffusion’ nearly two centuries ago. Subsequent explanations have refined this
Oxidation electronics: bond–band–barrier correlation and its applications
This report features the recent progress in understanding the behaviour of atoms and valence electrons involved in the process of oxidation, and some technological development driven by the new
Vibrational predissociation spectra and hydrogen-bond topologies of H+(H2O)9-11.
The results, combined with previously acquired spectra, show a systematic change in hydrogen-bond topology from tree-like, single-ring, multiple-ring to cage-like isomers (and their mixtures) as the cluster size increases from n = 5 to n = 11.
Dominance of broken bonds and nonbonding electrons at the nanoscale.
This article will focus on the development and applications of theory regarding the energetics and dynamics of nonbonding electrons, aiming to raise the awareness of their revolutionary impact to the society.
Structure and vibrational spectra of small water clusters from first principles simulations.
The structure and vibrational spectra of (H(2)O)(n) (n=2-5) clusters have been studied and show that water molecules in cluster are bound more tightly and there are significant broadenings of the spectra with temperature caused by thermal motions.
Size dependence of nanostructures: Impact of bond order deficiency
This report deals with the mechanism behind the unusual behavior of nanostructures in mechanical strength, thermal stability, acoustics (lattice dynamics), photonics, electronics, magnetism,
Frequency response of graphene phonons to heating and compression
The thermally softened and the mechanically stiffened graphene phonons have been formulated from the perspective of bond order-length-strength correlation with confirmation of the C–C bond length in
Thermo-mechanical behavior of low-dimensional systems: The local bond average approach
Abstract With the miniaturization of a solid, effects of surface strain and quantum trapping become increasingly important in determining its properties. As a result, low-dimensional materials
Spectral Signatures of Hydrated Proton Vibrations in Water Clusters
This work reports how the vibrational spectrum of protonated water clusters evolves in the size range from 2 to 11 water molecules, revealing the pronounced spectral impact of subtle changes in the hydration environment.
