(NMR) Nuclear Magnetic Resonance is a physical phenomenon of the magnetic property of nuclei, which have a positive nuclear spin quantum number.
Under the influence of an external static magnetic field this nuclei will precess about the direction of the magnetic field with an angular frequency (Larmor frequency). Through absorption and emission of RF energy (gradients, RF coils) at the resonance frequency (Larmor equation) and the processing of this raw data by the Fourier transformation - physical, chemical, electronic, and structural information about molecules can be obtained (NMR Magnetic Resonance Spectroscopy, Magnetic Resonance Imaging).

Nuclear Magnetic Resonance Signal
 
The electromagnetic signal in the radio-frequency range produced by the precession of the transverse magnetization of the spins. The rotation of the transverse magnetization induces a voltage in a receiving antenna (coil), which is amplified and demodulated by the receiver circuits. Electromagnetic signal in the radio frequency range produced by the precession of the transverse magnetization of the spins. The rotation of the transverse magnetization induces a voltage in a coil, which is amplified and demodulated by the receiver;; the signal may refer only to this induced voltage.

Nuclear Magnetic Resonance ImagingMRI Resource Directory:
 - NMR -
 
Creation of images of objects such as the body by use of the nuclear magnetic resonance phenomenon. The immediate practical application involves imaging the distribution of hydrogen nuclei (protons) in the body. The image brightness in a given region depends on the spin density and the relaxation times, with their relative importance determined by the particular imaging technique employed. Image brightness is also affected by motion such as blood flow. See also Zeugmatography and Magnetic Resonance Imaging MRI.

Spectroscopic Imaging Techniques
 
For the wide uses of NMR spectroscopy (from mineralogy to medicine) there is a variety of different spectroscopic imaging techniques available.
A short listing of the most frequent variations:
'One-dimensional NMR Spectroscopy (1D NMR) is attended to the spectra of (1H) Proton, 13Carbon etc., which in general is divided in continuous wave and pulse spectroscopy. General used to determine chemical structures. Proton nuclear magnetic resonance (1H-NMR) spectroscopy and carbon nuclear magnetic resonance (13C-NMR) spectroscopy are the most prominent techniques here.
'Two-dimensional NMR Spectroscopy' (2D NMR) is based on pulse spectroscopy. This technique is mostly used for the study of chemical interactions accompanied by magnetization transfer. Examples for more diversified spectroscopy techniques are based on homonuclear (COSY, TOCSY, 2D-INADEQUATE, NOESY, ROESY) or heteronuclear correlation (HSQC, HMQC, HMBC).
'Solid State NMR Spectroscopy' analyzes samples with little or no molecular mobility. Dipolar coupling and chemical shift anisotropy are the dominating nuclear physical effects here. Used for example in pharmaceutical analysis.
'Solution State NMR Spectroscopy' is a technique to analyze the structure of samples with a high degree of molecular mobility as polymers, proteins, nucleic acids etc..
