Nuclear magnetic resonance (NMR) spectroscopy is an analytical tool used to identify the structure and composition of molecules. It is based on the principle that the nuclei of certain atoms have a magnetic property called spin. When placed in a magnetic field, these nuclei align themselves either with or against the field, depending on their spin.

NMR spectroscopy can be used to determine the structure of a molecule by measuring the alignment of the nuclei in the presence of a magnetic field. The strength of the magnetic field and the frequency of the radio waves used to create the field are carefully controlled to produce the desired effect.

The nuclei of some atoms, such as hydrogen, have a spin that can be used to identify the molecule. The spin of the nucleus creates a magnetic field that can be detected by NMR spectroscopy. The strength of the magnetic field and the frequency of the radio waves used to create the field are carefully controlled to produce the desired effect.

NMR spectroscopy can also be used to identify the composition of a molecule. The composition of a molecule can be determined by measuring the amount of each element in the molecule. The amount of each element in a molecule can be determined by measuring the intensity of the signal produced by the element.
