FTIR

Presentation

Fourier Transform Infrared Spectroscopy (FTIR) uses infrared radiation to probe the vibrational transitions of a sample (molecules / proteins / materials). These transitions provide information on its structure and composition. In addition, differential FTIR spectroscopy is a powerful technique that provides information on the chemical groups and/or amino acids involved when conditions change (pH, temperature, light, substrate…)

The FTIR platform, located at the Laboratory of Fundamental Mechanisms in Bioenergetics (UMR 9198), is equipped to meet most of the needs of FTIR analysis. It includes 3 spectrometers with several accessories: transmission cell, ATR and SEIRA accessories, electrochemical cell, thermostat, cryostat for low temperature experiments… Samples in different forms (liquid, solid, powder..) can be studied.

The laboratory is specialized in the study of biochemical reactions and (photo)catalysis. We are particularly interested in the study of light-induced photophysical processes (electron/proton transfer) involved in reactions in solution or in proteins. For this, we rely on time-resolved measurements of absorption changes (100 ns – ms) and modeling.
