I didn't read that detail a description Crow. Sounds kinda like nuclear magnetic resonance (NMR). Ya put a sample in a strong magnetic field and hit it with radio waves which provides just the right quanta of energy to flip the magnetic dipoles of the hydrogen atom (proton).

The spectrum of the radio wave absorption peaks provides information on the structure of the chemical sample.

Once high performance computers become affordable, they took the extensive NMR spectral data base and used it to provide imaging of the different bodily tissues and called it MRI.

But still, a very strong magnetic field is required for NMR.
