H2O or H1.5O? Water Mystery Solved
http://www.livescience.com/forcesofnature/050524_water_H15O.html"No matter how long you look at it, a water molecule is still just two hydrogens latched onto one oxygen.
So says a new experiment, which contradicts a previous claim that water lost at least half of a hydrogen – effectively becoming H1.5O – when looked at with an extremely fast "camera."
...
An earlier experiment found that the neutrons scattered as if there were only one and a half hydrogens to every oxygen. These surprising results were explained by assuming that the two hydrogens are very briefly "entangled" with each other.
...
But new neutron pictures taken at Rensselaer Polytechnic Institute find two hydrogens even with exposure times of as little as 0.001 femtoseconds. At this shorter timescale, theory would have expected to see fewer hydrogens if entanglement truly was occurring.
..."Glad we've got that cleared up. Now I can take a shower again without wondering!
