Abstract
THE first demonstration that molecules differing only in their isotopic constitution could be separated by the technique of gas chromatography was made by Wilzbach and Riesz1, who used a packed column to separate deuterated and tritiated cyclohexanes. Later, Cartoni et al.2 showed that capillary columns were more efficient for this purpose, and achieved a separation of all the deuterated benzenes on a 500-ft. column. Cvetanovic3 demonstrated the value of this technique in the examination of radical reactions, being able to separate the products of the combination of protonated and deuterated alkyl radicals.
