WebCh 13 - NMR Chemical Shift. Chemical Shift. An NMR spectrum is a plot of the radio frequency applied against absorption. A signal in the spectrum is referred to as a resonance. The frequency of a signal is known as its chemical shift, d. The chemical shift in absolute terms is defined by the frequency of the resonance expressed with reference ... WebChemical shift. In nuclear magnetic resonance (NMR) spectroscopy, the chemical shift is the resonant frequency of an atomic nucleus relative to a standard in a magnetic field. Often the position and number of chemical shifts are diagnostic of the structure of a molecule. [1] [2] [3] Chemical shifts are also used to describe signals in other ...
