Resonant Frequency of water molecule

Resonant Frequency of water molecule

Resonant Frequency of water molecule

I am embarking on a study to determine whether a water molecule can be destroyed by forcing it to vibrate at is resonant frequency.  Any information will be appreciated.

RE: Resonant Frequency of water molecule

That's how a microwave works. Just vibates at ressonance. You can make steam, but I doubt you'll get H2 and O2.

RE: Resonant Frequency of water molecule

I have heard, but have not tested that by apply a frequency approx, 42KHz, H2o can be separated.

RE: Resonant Frequency of water molecule

Approx, how many db's would it take to seperate the water?

RE: Resonant Frequency of water molecule

I read that at 2,500 megahertz (2.5 gigahertz) radio waves are absorbed by water, fats and sugars. the mricrowave principle

RE: Resonant Frequency of water molecule

If you could get the atoms in the molecule to vibrate at the resonant frequency with the bonds acting as springs, it would destroy the atom as long as the vibrations were not damped out before they could "add" to each other. Also, mocrowaves do not cause a molecule to vibrate like a mass-spring system, but to rotate and rub against each other. So the problem becomes how to get the molecules to vibrate like a mass-spring system.

RE: Resonant Frequency of water molecule

According to information at this web site : http://www.keelynet.com/energy/docx.htm

making water vibrate at its resonant frequency can be more than a little dangerous.  Use caution.

RE: Resonant Frequency of water molecule

The H2O molecule can be destroyed at 2000 grad Cetigrad, to achive that only heat is necessary.

RE: Resonant Frequency of water molecule

How do you plan to "make it vibrate"?

I have read up on extracting H2 from water, and thermally assisted electrolysis was discussed quite a bit.

According to some sources I read, water thermally decomposes into H2 and O2 at about 5000 centigrade.

If all you want is to crack water molecules, brute-force heat will do it.

Now, if you're looking for ways of generating hydrogen without the brute force method, using radio waves (microwaves) to crack steam might be an approach to try.

Just a few thoughts.  :)

RE: Resonant Frequency of water molecule

For a completely different spin on this, what happens when I strap on a 2.4-2.5 GHz headphone on?   Are the water molecules in my head resonating?  How much power is too much?

RE: Resonant Frequency of water molecule

Surely any resonance that would happen on an atomic level would be damped out by macroscopic motion of the liquid?

Can a liquid HAVE a resonant frequency?

Could you explain a bit more of your theory?

Many thanks, HM
