Vibrational excitations of proteins and their hydration water in the far-infrared range

- We characterize the vibrations of proteins and hydration water in far-infrared range.
- Isotopic contrast is used to highlight protein or water component.
- MD simulations help understanding vibrational bands.
- The inelastic behavior of proteins is quite independent on the solvent.
- Protein hydration water vibrational behavior is similar to amorphous ice.
