Motion in the Ocean?

Posted June 04, 2010 7:21 AM

Using a microscope and a series of laser pulses and detectors, scientists have captured a complex molecular dance within a simple glass of water (see video simulation). In a series of intricate experiments, the researchers showed that the hydrogen bonds between water molecules are repeatedly breaking and reforming at the rate of one hundred billion times per second.

The preceding article is a "sneak peek" from Lab Equipment, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Lab Equipment today.

Interesting study. I always believed that water was very active at the molecular level but believed it was more stable at depth. That still may be the case and the activity does explain evaporation in a way that we can understand. It also explains oxidation in the shallower depths of the ocean. But, another way of looking at this study is to think that water is stable. If we allow 1 picosecond for the change then water is stable for 5 picoseconds or 5/6 of the time or 83% of the time, about expected I think. Now that we know about this dance, to what advantage can we apply to the knowledge? Can we also relate the dance to pressure when everything gets harder to change?

Does that frequency:- 160 billion times a second change with temperature?
