Can we break the covalent bonds of water molecules $\ce{H2O}$ using resonance frequencies? What is the wavelegth of the water's molecule? Can we create a vibration like this and use it to separate hydrogen from oxygen?


Yes this is possible. Your question does not state the source of the frequency, but in this internet article they have used laser light.

I am not sure at what frequency you need to irradiate water to break the O-H bond, but I would speculate that a good frequency would be close to the IR stretching frequencies of the O-H bond in water.

    $\begingroup$ I think a better frequency would be one that excites electrons … $\endgroup$ – Jan Dec 30 '15 at 22:53
  • $\begingroup$ You'll need to get above the ground electronic state, as @Jan notes. And I think the OP needs to chime in with respect to the part about separating hydrogen and oxygen: do you mean as charged species, radicals, diatomic gases, or what? $\endgroup$ – Todd Minehardt Dec 31 '15 at 0:52

    $\begingroup$ @Jan. That was also my initial guess, but as soon as you start exciting the electronic levels, the geometry of the molecule gets distorted and you are no longer 'pumping' at the right frequency to break the bond. I don't think it is possible then to break a specific bond. That's why my suggestion was to slowly 'pump' the vibrational levels until the bond breaks. In other words, you would like to stay as close to ground state chemistry. I haven't found the article though where the procedure is given. $\endgroup$ – Ivo Filot Dec 31 '15 at 13:23
  • $\begingroup$ In the article, they excite surface Si-H bonds. I suspect that being on a surface really helps prevent transfer of energy to other motions by collision. In liquid H2O, I suspect you would just heat the solution rather than break bonds very often, though maybe there's a laser that could deliver energy fast enough to overcome this. $\endgroup$ – Andrew Aug 6 '19 at 12:03

The resonate frequency of water is 632 hz. The covalent bond can be easily broken using 12v of DC current at as little as 5amps. The Hydrogen and Oxygen can be separated or collected together in the form of Browns gas or HHO. I use it in my car.
