A sample is exposed to powerful magnetic fields, in order to align the particles. Magnetic spins of the electrons of the Hydrogen atoms. They align in the most favorable (lowest energy) alignment. Then the sample is blasting with varying frequencies of electric field (up to 300million Hz) and the frequency at which the electrons move out of alignment is recorded. This information is then used to determine structures of molecules. (Can you tell that I'm a biochem major?)

			The application of this method stems from the understanding of how these waves interact with the charged particles of matter. Our models for atoms and electromagnetic waves allow us to make useful and accurate predictions about chemical structure. It is also a great tool for stressing out aspiring biochem majors. (Reading NMR graphs is very difficult. Google it. You'll see what I mean.)

	~~#How~~ is ~~this topic connected to something~~ that ~~you~~ are ~~interested~~ in?		This model of electromagnetic waves allows us to predict the effects of light and other waves on matter. We know that light can be polarized into one direction, which is practical for use in optics. We also can determine the interaction between these waves and charged particles. For instance, one important idea is that electromagnetic waves carry energy. Chemists use the properties of light energy in techniques called spectroscopy. Magnetic and electric waves and fields are critical in determining structure of unknown molecules.
