NMR – Nuclear Magnetic Resonance
The nuclear magnetic resonance is of great importance for organic chemistry.
It is used for the analysis of organic and organometallic substances as well as for structural chemical issues. The method analyzes the behavior of magnetically active atoms under the influence of a high-frequency magnetic field. Absorption and emission of alternating magnetic fields change the orientation of the nuclear spins to the magnetic field.
The prerequisite for analyses is a nuclear spin unequal zero. Isotopes with an even proton and neutron number are unsuitable for the method.
Generally, samples are analyzed in deuterated solvents. In addition, solid samples can also be analyzed by solid-state NMR.
Typically analyzed isotopes include: 1H; 10B; 11B; 13C; 15N; 17O; 19F; 31P, 29Si
