摘要: Abstract There is little doubt that liquid water consists of molecules joined together to a considerable extent by hydrogen bonds. The assumption the principal aggregates in have structure similar ice or an analogous quartz-like not compatible with some properties and theoretical arguments. A for has now been proposed seems be acceptable as first approximation. This may described involving complexes 21 molecules, icosahedral symmetry, still larger complexes, perhaps 41 molecules. are stable rigid, but labile.
