Webb27 feb. 2015 · On February 27, 1940, Martin Kamen and Samuel Ruben confirmed the existence of the carbon isotope 14 C. Working at the University of California, Berkeley, … WebbRuben conducted an experiment by labelling the oxygen of water with O 18. The oxygen evolved during photolysis contained O 18 . He also prepared a source of carbon dioxide that was enriched in O 18. The oxygen evolved was not comprised of labelled O 18 isotope. So, it was proved that oxygen evolved was from water molecules not carbon dioxide.

Ruben and colleague Martin Kamen, a University of Chicago Ph.D. and researcher in chemistry and nuclear physics working under Ernest O. Lawrence at the Berkeley Radiation Laboratory, set out to elucidate the path of carbon in photosynthesis by incorporating the short-lived radioactive isotope carbon-11 ( CO 2) in their many experiments between 1938 and 1942. Aided by the concepts and collaboration of C.
