Shielding and Deshielding - H NMR Spectroscopy

This organic chemistry video tutorial discusses shielding and deshielding as it relates to H-NMR spectroscopy. A hydrogen nucleus is said to be shielded from an external magnetic field if it is an electron rich environment. It will thus appear upfield in the NMR spectrum. Protons adjacent to electron withdrawing group are said to be deshielded and appear downfield in a NMR spectrum.
