WebAug 28, 2024 · Nuclear magnetic resonance spectroscopy (NMR) is a widely used and powerful method that takes advantage of the magnetic properties of certain nuclei. The basic principle behind NMR is that some nuclei exist in specific nuclear spin states when exposed to an external magnetic field. WebTo accurately select a very small section of the spectrum, one would have to make an extremely narrow slit. Since this is very hard to do at home, I chose to make two slits instead that are not 100% aligned, so only a very narrow band of light can pass through. Make a small slit in a piece of metal or cardboard.
