Hi. I was doing a few ¹H NMR runs and was thinking why NMR gives out the best pieces of physical evidence for pi electron delocalization in armoatic rings? (besides the fact that the sample does not get destroyed :p ) Is it also because of the coupling that takes place due to the strong magnets in the NMR machine? I'm not really a physical chemist and I didn't know how to explain it to my friend. 

Thanks

Dear CopperSmurf;

What you name “Coupling“ should mean “Resonance”, but you can also observe “Couplings” inside a NMR-Spectrum.
And all this does not "work" with л-Electrons, but is (the “Coupling”) influenced from them.

Maybe to get a small overview of NMR you visit:   "NMR Spectroscopy”.
And also:    "Nuclear Magnetic Resonance”.

I hope I have been of help to you.

Good Luck!
