WebNov 17, 2024 · NMR is great for any type of nucleus that has an odd mass number. For most organic chemistry courses, you collect 1 H (proton) and 13 C (carbon-13) NMR spectra. Samples are usually in solution, because allowing the molecules to move freely will help average their signals. Other techniques are possible. WebVideo transcript. - The nucleus of a Hydrogen atom is a proton and has a property called spin. So you can think about, just as a visual aid, you can think about this proton that's spinning this way. A spinning proton, right, is like a rotating sphere of charge, and any moving charge creates a magnetic field.
