Abstract

L'invention concerne un procédé pour séparer et enrichir des molécules contenant du deutérium. Selon l'invention, on prévoit une source de molécules organiques 10 contenant des atomes de deutérium, et qui ont une formule structurelle RX, où R est un radical organique choisi dans le groupe consistant en éthyle, isopropyle, t-butyle, et 3-cyclopentényle et où X est choisi parmi F, Cl, Br et OH, on expose des molécules au rayonnement d'au moins une source à laser infrarouge A spécifiquement accordée et focalisée pour sélectivement décomposer des molécules RX contenant du deutérium et former une oléfine enrichie contenant du deutérium et HX; et on sépare en B l'oléfine des molécules RX épuisées en deutérium et non décomposées et de HX. L'invention s'applique notamment à l'industrie nucléaire.
