NMRexperiment
NMR experiment refers to any measurement that uses nuclear magnetic resonance to obtain information about the structure, dynamics, or environment of molecules. In a typical NMR experiment, a sample containing nuclei with nonzero spin is placed in a strong static magnetic field. Nuclei have characteristic Larmor frequencies that depend on the magnetic field and their gyromagnetic ratio. An applied radiofrequency pulse perturbs the nuclear spins, and the resulting spin precession induces a detectable signal, known as the free induction decay. Fourier transformation converts this time-domain signal into a spectrum that shows resonance frequencies, intensities, and line shapes which reflect the chemical environment of the nuclei.
Commonly studied nuclei include hydrogen-1 (1H), carbon-13 (13C), nitrogen-15 (15N), and phosphorus-31 (31P). Experiments can be
Samples are typically in solution, though solid-state NMR is used for materials and immobilized systems. Preparation
