Continuous Wave NMR
 
(CW) A technique for studying NMR by continuously applying RF radiation to the sample and slowly sweeping either the RF frequency or the magnetic field through the resonance values; now largely superceded by pulse MR technique.

Adiabatic Fast Passage
 
(AFP) Adiabatic fast passage is a NMR technique of producing rotation of the macroscopic magnetization vector by shifting the frequency of RF energy pulses (or the strength of the magnetic field) through resonance (the Larmor frequency) in a time short compared to the relaxation times. Particularly used for inversion of the spins between high and low energy states with an excess of spins in the higher energy level. A continuous wave NMR technique used in e.g., MR spectroscopy.

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.
