Abstract :
The use of the far IR spectral range presents a novel approach for analysis of proteins. Here it is presented for the analysis of Fe-S vibrations (500-200 cm-1) and of the intra-and intermolecular H-bonding signature (300-50 cm-1) in Rieske proteins and lipids in function of T, redox state and pH.
