350 px|thumb|Isotopomers of isotopically modified ethanol. The molecule at the bottom left is not an isotopomer of any other depicted molecule. Isotopomers or isotopic isomers are isomers which differ by isotopic substitution, and which have the same number of atoms of each isotope but in a different arrangement. For example, CH3OD and CH2DOH are two isotopomers of monodeuterated methanol.

For example, CH3OD and CH2DOH are two isotopomers of monodeuterated methanol.
The molecules may be either structural isomers (constitutional isomers) or stereoisomers depending on the location of the isotopes. Isotopomers have applications in areas including nuclear magnetic resonance spectroscopy, reaction kinetics, and biochemistry.
