Definitions:

Diastereotopic

Describes hydrogen atoms (or groups) in a molecule that are not equivalent in the three-dimensional space, causing different chemical shifts in NMR spectroscopy.

Enantiotopic

Refers to two groups or atoms in a molecule that are mirror images of each other but are not superimposable, commonly used in stereochemistry.

Internal Reference

A benchmark or standard within an experiment or measurement against which other data or results are compared or calibrated.

Deshielded Proton

A proton in an NMR spectrum that appears at lower field due to its electron cloud being less shielded from external magnetic fields, often indicating an electron-withdrawing group nearby.
