On Water Density Fluctuations with Helices of Hydrogen Bonds

Abstract: An adaptive model is developed here for the liquid water density fluctuations as momentary dense clusters with helices of hydrogen bonds and nondense tetrahedral clusters of ice. This model can be useful for explanation of liquid water structural anomalies including the high quantity of hydrogen bonds with quasitetrahedral orientation in the nonordered liquid water. The topology of such clusters is essentially differed from the one of the crystalline ice. From this and only this point of view, the liquid water… Show more

“…One can expect that water molecules have enough time for rebuilding hydrogen bonds in a dense part of water density fluctuations due to very fast librations and rotations of them in liquid phase. From this, the model for instant dense clusters [22] is built with helices of hydrogen bonds (see Figure 1(b)). All angles between them are equal to 106.8 • .…”

“…From this and only this point of view, the liquid water is considered as a twostructural fluid by dynamic forming the two topological kinds of clusters in density fluctuations. The mole fraction of helical clusters in liquid water can amount to 0.6 [22].…”

“…В работе [9] теоретически обосновали образование в тетраэдрической сетке водородных связей кластеров в виде спиральных цепочек из тетраэдров, в которых протоны совершают когерентные колебания. Очевидно, что образованию спиральных кластеров будет способствовать внешнее электромагнитное излучение, резонирующее с частотой колебаний протонов.…”
