The strict regiospecificity of the labelling in some monotritiated glucoses, available commercially as aqueous solutions, is demonstrated by 3H n. m. r. spectroscopy. After storage there may however sometimes be label also present in the water or as

The regio- and stereo-specificity of the labelling in a series of tritiated steroid hormones has been examined by 3H n.m.r., which also yields quantitative information on the distribution of the tritium between the labelled sites. Complete analysis i
