How does chirality effect nmr?

Answer 1

A left handed stereoisomer would give precisely the same NMR spectrum as the right handed stereoisomer in the standard experiment. How do I know this?

In a typical experiment, enantiotopic nuclei on the same molecule produce the same NMR signal; however, if a chiral NMR solvent is employed (which is possible), the enantiotopic nuclei should result in distinct absorptions.

Keep in mind that enantiotopic nuclei are those that can only be switched by an incorrect rotational axis, such as a mirror plane.

Chirality affects NMR by causing different chemical shifts for enantiomers in a chiral environment due to interactions with chiral molecules or environments, such as chiral solvents or chiral ligands. This phenomenon is known as the chiral discrimination effect in NMR spectroscopy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
