intramolecular isotope effect
A @K03405@ observed when a single substrate, in which the isotopic atoms occupy equivalent reactive positions, reacts to produce a non-statistical distribution of @I03352@ products. In such a case the @I03327@ will favour the pathway with lower @F02481@ for displacement of the isotopic nuclei in the @T06468@.
