Fourier Transform Infra Red (FTIR) spectroscopy allows to analyze the secondary structure of macromolecules by measuring absorption frequencies of some specific chemical groups (notably, for proteins that of the amide bond).
Informations given by FTIR are complementary to those obtained bycircular dichroism and are more specifically suited for the precise study of the ß content of proteins.
The device available at the PFBMI is a MB104 from ABB, equipped with an Attenuated Total Reflectance (ATR) accessory (DuraSamplIR, SensIR).
