Protein Structure and Dynamics

In this communication the first IR/R2PI (infrared/resonant two-photon ionisation) spectra of CO stretching vibrations are presented applied to a β-sheet model system. CO vibrations are extremely important to describe the structure of isolated peptides and especially the hydrogen bonding in β-sheet related structures in the gas phase.
