Isotopomeric ion
IUPAC RECOMMENDATIONS 2013
Isomeric ions having the same numbers of each isotopic atom but differing in their positions within the ion. Note 1: Examples are D₂C=CH₂^+• and HDC=CHD^+•. Note 2: Isotopomeric ions can be either configurational isomers in which two atomic isotopes exchange positions or isotopic stereoisomers. Note 3: Isotopomer is an abbreviation of isotopic isomer.

http://goldbook.iupac.org/I03352.html isotopomer Isomers having the same number of each isotopic atom but differing in their positions. The term is a contraction of 'isotopic isomer'. Isotopomers can be either constitutional isomers (e.g. CH2DCH O and CH3CD O) or isotopic stereoisomers [e.g. (R)- and (S)-CH3CHDOH or (Z)- and (E)-CH3CH CHD].
