In the context of Nuclear Magnetic Resonance (NMR) spectrometry, the following terms are fundamental to understanding how the technique works:

Chemical Shift:
Chemical shift refers to the variation in the resonance frequency of nuclei in a molecule when placed in a magnetic field. It is caused by the shielding or deshielding effects of the surrounding electrons. Nuclei in different chemical environments experience slightly different magnetic fields, leading to shifts in the resonant frequencies.
