Water can Dance – And really it does.
Quantum theory have long described the importance of the hydrogen binding network but the knowledge have been purely theoretical. Now we can see that water can switch dance partner About once every six picoseconds.
And that will be around 160 billion times a second.
If the water changes the way the molecules vibrate or just the axis of the molecules, then the major part of you will change. Can you ever believe that a change in the matter that make you, will change you?
“We found that the hydrogen bond breaks and reforms with an angular jump of about 50 degrees,” Gaffney said. “And that’s about what simulations performed by Michael Odelius suggested.”
The method used by Gaffney and his team to measure the bond lifetime and angle worked well for water and perchlorate, but is not possible with pure water; when all water molecules form the same hydrogen bonds, there is no way for the researchers to tell when they have switched partners. Fortunately, Gaffney said, all simulations seem to imply that the results found for salt water apply to pure water and a variety of aqueous solutions.
“This is exciting work,” Ji said. “To really understand water, the stuff that makes up more than half our bodies, we need to understand how these molecules move in a microscopic field. But it’s only with the recent development of ultrafast lasers that we’ve been able to measure the time scale of these small molecules.”
Will water ever make sense in your matter?
Hydrogen bonds (H-bonds) provide the intermolecular adhesion that dictates the unique properties of liquid water and aqueous solutions. Although H-bonds constrain the local ordering and orientation of molecules in solution, these local H-bond networks disband and reform on the picosecond time scale. This structural lability critically influences chemical and biological transformations.
