The nitrogen in the compound can have a deshielding effect on the nearby hydrogens. This occurs because nitrogen is more electronegative than hydrogen, which means it pulls electron density away from the hydrogen atoms that are in proximity to it.
When the nitrogen atom attracts electrons, it creates a situation where the local magnetic field around the nearby hydrogen nuclei is weakened. This weakening of the magnetic field means that those hydrogens are less shielded from the external magnetic field used in techniques like NMR (Nuclear Magnetic Resonance) spectroscopy. As a result, the resonance frequencies of these hydrogen nuclei will shift downfield, indicating a deshielding effect.
In summary, the presence of nitrogen nearby tends to deshield the hydrogens, leading to a shift in their observed chemical environment in spectroscopic analysis.
