## Abstract ^1^H‐Nmr was used to measure the rate of __cis__–__trans__ interconversion of __X__‐Pro bonds in linear and cyclic oligopeptides. __k__(cis → trans) = 2.5 × 10^−3^ s^−1^ at 25°C was found for the zwitterionic form of H‐Ala‐Pro‐OH, in good agreement with earlier measurements. Replacement
