Chemical shift δ is usually expressed in parts per million (ppm) by frequency, because it is calculated from: where νsample is the absolute resonance frequency of the sample and νref is the absolute resonance frequency of a standard reference compound, measured in the same applied magnetic field B0. Since the numerator is usually expressed in hertz, and the denominator in megahertz, δ i…
