The motion of a single water ligand around a peptide bond in acetanilide was probed in real time by time‐resolved IR spectroscopy. In their Communication on page 6604 ff. , O. Dopfer, M. Fujii et al. observe that triggered by photo‐ionization, the H 2 O ligand is released from the CO site of the peptide linkage and trapped after a migration time of 5 ps at the NH site of the same peptide bond. The migration occurs via an intermediate in which the H 2 O molecule binds neither to the CO nor the NH site.
