NMR:

* Nuclear simply means we are concerned with the nucleus of the atoms we are interested in (so the protons and neutrons).

* '''Nuclear''' simply means we are concerned with the nucleus of the atoms we are interested in (so the protons and neutrons).

* In essence, any atoms that have an odd number of protons or neutrons (or both) will behave like magnets. This is due to their '[https://en.wikipedia.org/wiki/Spin_(physics) spin]'. These are commonly referred to as "NMR active" (Common ones being Hydrogen-1 and Carbon-13).

* By exposing atoms to a magnetic field and RF of a given frequency, we can put them into resonance. This can be measured, and is the basis for the technique.

Whereas other spectroscopic techniques are concerned with the electrons of an atom. [https://www.youtube.com/watch?v=TJhVotrZt9I Nonetheless, the electrons surrounding an atom influence how much the nucleus is "diamagneticically shielded" from the effects of the RF of the NMR.] This allows Hydrogen atoms in different states to be observed.
