isotopomeric ion

https://doi.org/10.1351/goldbook.12455
Isomeric ions having the same numbers of each isotopic atom but differing in their positions within the ion.
Notes:
  1. Isotopomeric ions can be either configurational isomers in which two atomic isotopes exchange positions or isotopic stereoisomers.
  2. Isotopomer is an abbreviation of isotopic isomer.
Example: \(\ce{D2C=CH2^{+.}}\) and \(\ce{HDC=CHD^{+.}}\).
