Supercooled water dynamics involve transitions between inherent structures (IS) driven by hydrogen bond changes. Molecules move in small, branched clusters during these IS shifts, differing from simpler liquids.

Area of Science:

  • Condensed matter physics
  • Physical chemistry
  • Computational chemistry

Background:

  • The energy landscape approach aids in understanding supercooled liquids and their thermodynamics.
  • Analyzing inherent structure (IS) trajectories filters out vibrations, revealing slow structural dynamics.

Purpose of the Study:

  • Investigate IS trajectories in a water model.
  • Analyze changes in hydrogen bond connectivity during IS transitions.
  • Characterize molecular motion and clustering during IS changes.

Main Methods:

  • Numerical modeling of a 216-molecule water system.
  • Analysis of inherent structure (IS) trajectories.
  • Tracking hydrogen bond network modifications and molecular displacements.

Main Results:

  • IS transitions in water are driven by hydrogen bond network rearrangements (linear to bifurcated bonds).
  • These transitions occur on a femtosecond timescale, with small energy barriers.
  • Molecules move in small (1-10 molecules), branched clusters, distinct from stringlike clusters in other liquids.

Conclusions:

  • Water's slow structural relaxation arises from numerous small IS transitions.
  • Molecular clusters in supercooled water exhibit branched structures, differing from simpler liquids.
  • Hydrogen bond dynamics are central to the energy landscape and dynamics of supercooled water.
