Small, but very significant : Partial separation of two hemicarceplexes which differed only in the degree of guest deuteration could be achieved by normal‐phase chromatography (see picture). The difference in retention time arises from a variation in the interaction between the hemicarceplex and the silica surface as a consequence of a 0.005‐Å difference in the CH and CD bond lengths of the guest molecules.
