ANALYSIS OF 1H NMR SPECTRA
1. What is chemical shift?

2. What is shielding and deshielding?
Deshielding: The electrons around the proton create a magnetic field that opposes the applied
field. This reduces the field experienced at the nucleus and therefore decreases the freqency
required for the absorption
Shielding: The electrons around the proton create a magnetic field that reinforces the applied
field. This increases the field experienced at the nucleus and therefore increases the freqency
required for the absorption
