Notes on nmr
WebNuclear Magnetic Resonance (NMR) spectroscopy is (arguably) the most powerful tool available for determining the structure of organic compounds. This technique relies on the ability of atomic nuclei to behave like a small magnet and align themselves with an … WebNote : Two types of hydrogens, the hydrogens of a methyl are the same- they spin and experience the same average environment. The oxygen pulls electrons away from the right methyl and it is deshielded from the applied field, shifted downfield, a smaller field is needed to bring it into resonance. Three kinds of carbon.
