Isotopomers or isotopic isomers are isomers with isotopic atoms, having the same number of each isotope of each element but differing in their positions. The result is that the molecules are either constitutional isomers or stereoisomers solely based on isotopic location.For example: CH3CHDCH3 and CH3CH2CH2D are a pair of constitutional isotopomers of propane. (R)- and (S)-CH3CHDOH are isotopic stereoisomers of ethanol. (Z)- and (E)-CH3CH=CHD are examples of isotopic stereoisomers of propene.

  • Izotopomery (izotopické izomery) jsou molekuly – izomery které mají navzájem stejný počet izotopických atomů umístěných v různých polohách. Například CH3CHDCH3 a CH3CH2CH2D tvoří dvojici izotopomerů odvozených od propanu; vždy jeden z atomů vodíku je nahrazen atomem deuteria. (cs)
  • Gli isotopomeri o isomeri isotopici sono isomeri che contengono i medesimi atomi isotopici ma disposti in posizioni differenti. Il termine deriva per contrazione da isotopi isomeri. A seconda di come sono disposti gli isotopi, gli isotopomeri possono dar luogo a isomeri costituzionali o a stereoisomeri. Ad esempio gli isotopomeri CH3CHDCH3 e CH3CH2CH2D sono una coppia di isomeri costituzionali del propano. (R)- e (S)-CH3CHDOH o (Z)- e (E)-CH3CH=CHD sono esempi di stereoisomeri isotopici rispettivamente dell'etanolo e del propene. (it)
  • Um isotopômero ou isômero isotópico são isômeros com átomos isotópico, tendo o mesmo número de cada isótopo de cada elemento, mas diferindo em suas posições. O resultado é que as moléculas são isômeros constitucionais ou estereoisômeros somente com base na localização isotópica. Por exemplo, CH3CHDCH3 e CH3CH2CH2D são um par de isotopômeros constitucionais de propano. (R)- e (S)-CH3CHDOH ou (Z)- e (E)-CH3CH=CHD são exemplos de estereoisômeros isotópicos de etanol e de propeno, respectivamente.O termo isotopômero foi primeiro proposto por e Paine em 1992 para distinguir isômeros isotópicos de isotopólogos (homólogos isotópicos).

  • Isotopomeren zijn isomeren die dezelfde isotopische samenstelling bezitten, maar de plaats waar zij voorkomen in de molecule verschilt. Isotopen zijn atomen van dezelfde soort, maar zij verschillen in het aantal neutronen in de kern. De term is een samentrekking van isotopische isomeren. Isotopomeren kunnen gebruikt worden bij het achterhalen van een bepaald reactiemechanisme, omdat de atomen kunnen gevolgd worden in hun verplaatsingen tijdens een reactie. (nl)

Isotopen zijn atomen van dezelfde soort, maar zij verschillen in het aantal neutronen in de kern. De term is een samentrekking van isotopische isomeren. Een voorbeeld van structurele isotopomeren zijn de gedeutereerde varianten van propaan: CH3CHDCH3 en CH3CH2CH2D. In het eerste geval bevindt het deuterium zich op het middelste koolstofatoom, terwijl bij de tweede structuur het deuterium zich in de terminale methylgroep bevindt. Er zijn ook stereo-isotopomeren. Isotopomeren kunnen gebruikt worden bij het achterhalen van een bepaald reactiemechanisme, omdat de atomen kunnen gevolgd worden in hun verplaatsingen tijdens een reactie. (nl)
