First of all, All About Circuits is a great site and I am grateful for the chance to participate in the forums.

I heard about resonant dissociation of water at 42712.2 Hz & want to look into it. The details are in the attached PDF file.

 

Electrodes in water will deliver your resonance. Think of the electrodes as an anteana. Fron what I have read distance between the electrodes is related to the wavelength.

 

That's not really a useful circuit diagram. Googling "resonant dissociation of water" brings up sites that have much more information (although the ones claiming zero point energy are just on the fringe of true believers).
