Isotopomeric ion
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.

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].
