Abstract :
The far-infrared absorption of proteins is precisely measured at well-defined temperature and hydration. The absorption decreases with temperature and increases with hydration. The amount of water attached to the protein is calculated by a general sorption isotherm equation. Comparing this amount with the measured absorption the specific dynamic of the hydration shell can be extracted.
