A long and winding road : The motion of a single water ligand around a peptide bond in acetanilide was probed in real time by time‐resolved IR spectroscopy. Triggered by photoionization, 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 (see picture).
