Synergism of the dynamics of tetrahedral hydrogen bonds of liquid water

11 Feb 2021 Alexander Kholmanskiy

We used modified Arrhenius approximations to analyze the known temperature dependences (TDs) of water microstructure parameters and its dynamic characteristics. The analysis of activation energies showed a significant difference in the molecular dynamics (MD) of water in the ranges from 273 to 298 K and from 300 to 373 K. The features of MD in the first range were associated with the metastable ice-like phase of water, in which hexagonal clusters with tetrahedral hydrogen bonds (HBs) predominate... (read more)
