Isotopocules are isotopically substituted molecules, which differ only in their isotopic composition or their isotopes' intramolecular position.[1] "Isotopocule" is also an umbrella term for the more specific terms "isotopologue" and "isotopomer", coined by Jan Kaiser and Thomas Röckmann in 2008.[2][3]

Example of six stable isotopocules of ethanol (i.e. with stable isotopes) out of the total number of 288 stable isotopocules
