The chemical shift value (δ) is measured by the ratio of shift in Hertz and the operational frequency of the spectrometer in MHz, give the equation to calculate the shift value
Expert Solution
Step 1
In nmr spectroscopy chemical shift is expressed in terms of ppm as it is independent of applied magnetic field and instrument. If we record the spectra in 100MHz and 60MHz spectra, the chemical shift in ppm is same but if we expressed in precessional frequency they are different so we can't able to compare .
