ABSTRACT OF THE DISCLOSURE The present invention relates to deuterium isotope separation and enrichment and more particularly to deuter- ium isotope separation and enrichment using infrared laser technology in combination with chemical processes. Deuter- ium occurs in nature to the extent of about 0.014%. Pre- sently, multi-stage equilibrium partition methods are employed to concentrate the naturally occurring deuterium. Such methods involve bulky equipment and large materials handling problems because of low enrichment factors per stage. Therefore, there is low throughput and long time periods involved in order to attain steady state equili- brium conditions. A present invention provides a method of separating deuterium from certain naturally occurring sources using tuned infrared lasers to selectively decom- pose specified classes of organic molecules (i.e. RX) into enriched molecular products containing deuterium atoms. The deuterium containing molecules are easily separated from the starting material by absorption, dis- tillation or other simple chemical separation techniques and methods. After evaporation such deuterium containing molecules can be burned to form water with an enriched deuterium content or pyrolyzed to form hydrogen gas with an enriched deuterium content. The undecomposed molecules and the other reaction products which are depleted of their deuterium containing species can be catalytically treated, preferably using normal water, to restore the natural abundance of deuterium and such restored molecules can then be recycled.
