Liquid water molecular structure

Researchers find evidence that liquid water switches between two hidden structures

A study in Nature Physics has found molecular-level evidence that liquid water can shift between two local structures, giving scientists a fresh clue to one of chemistry’s oldest puzzles. Using unsupervised deep learning and large molecular dynamics simulations, the research team identified patterns that support a long-debated idea called the two-state water model. The result…
