Watching Water Migration around a Peptide Bond

Abstract

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 H2O 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).
