technique used to determine the structure of molecules.
In NMR, the molecule
is placed within a strong magnetic field to align the atomic nuclei. An
oscillating electromagnetic field is applied, and the radiation absorbed or
emitted by the molecule
is measured. Not all atoms
can be detected using NMR because the nuclei must have non-zero magnetic
analytical method that can detect subatomic and structural information of molecules by measuring the adsorption of radio-frequency electromagnetic
radiation by nuclei under the influence of a magnetic field.
