Re: water microstructure

It is also my understanding that the crystal structure persists throughout the
temperature range at which water is liquid, but as the temperature increases,
the hexagonal structures become less numerous and less complete (ie, only
fragments of the hexagon are observed).

For a complete description of the properties of water, I think it would be hard
to beat the small book by Felix Franks. I've only read the first edition, but
Books in Print indicates that a second edition is now out:
Water. Franks, F., 2000 Water. ISBN: 085404583X, The Royal Society of

You might also be well served to read (and peruse the citations in)
Liu, K., et al. 1996. Characterization of a cage form of the water hexamer.
Nature 381: 501-503.

You're aquainted with the literature? I'm not, I've just seen a handful
of popular articles. Can you recommend any good books?

Articles say that liquid water has a short-range order which resembles
ice. It acts like a bunch of nano-crystals whose boundaries are
constantly changing because of thermal vibrations. Are you saying that the
crystalline microstructure only arises below a certain temperature? I was
under the impression that the microstructure was always there as long as
water was a liquid.
