Hi
My basic understanding of NMR is that the nucleus of an atom is like a little bar magnet and when placed in a magnetic field this magnet can align with the magnet (low energy state) or oppose the magnet (high energy). The nucleus can enter the opposed state when radio frequency radiation is applied. The specific frequency of radiation needed depends on the effective local magnetic field experienced by the nucleus.
I don't need an understanding any greater than the one give above.
One term I come across when reading is something like the following:
'bring the nucleus into resonance'
'when the nucleus is in resonance'
What does 'in resonance' mean at the level I am describing? Does it mean 'when the nucleus is in the high energy state opposed to the applied magnetic field?' It seems to from the context I read it in but I'd like to be sure
Thanks
