## Abstract The ^13^C chemical shifts and spin‐lattice relaxation times are reported for __cyclo__(L‐Pro‐L‐Leu) and __cyclo__(L‐Pro‐D‐Leu). The chemical shifts of the D and L leucyl residues in the cyclic peptides differ from each other by 1.8 and 3.6 parts per million for the α and β carbons, resp
