Used to study mechanisms and rates of chemical or nuclear reactions, as well as biological processes. [ChemIDplus] Deuterium oxide is present in nature. Water contains about 1 part per 6500. [Hawley]To study chemical reaction rates and mechanisms. The cross section of deuterium for the capture of thermal neutrons is very low which makes it useful, in the form of heavy water, as a neutron moderator in nuclear reactors. Produces a considerable decrease in neutron energy per collision.
