Resumen de A Short History of Three Chemical Shifts.
The distinctive term "chemical shift" to designate the position of a spectral signal is used in three forms of spectroscopy: nuclear magnetic resonance (NMR), electron spectroscopy for chemical analysis (ESCA), and Mössbauer spectroscopy. Regrettably, chemical shift has a poor reputation as a technical term. However, the "chemical" environment around an atom of interest influences the electronic environment and hence, leads to spectral shifts. Therefore, using the prefix "chemical" for the shifts observed in the three forms of spectroscopy is appropriate.
