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). With this technique, in spite of sounding scary, ionizing radiation is not involved (the actually scary part when you hear the world nuclear).
* 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.
