Chemically Equivalent
Describes atoms or groups in a molecule that are identical in their chemical environment, often resulting in indistinguishable spectroscopic signals.
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.
