Thierry Buffeteau receives Silver Medal 2011 of the CRNS

Thierry Buffeteau receives Silver Medal 2011 of the CRNSThierry Buffeteau, research director of the molecular spectroscopy group at the University of Science and Technology (Université Sciences et Technologies) in Bordeaux, has been awarded the Silver Medal 2011 from the National Scientific Research Center (CNRS: Centre National de la Recherche Scientifique, a government-funded research organization under the administrative authority of France's Ministry of Research).

The medal honours his achievements in determining the optical properties of multi-layered systems and monolayers deposited on metals based on polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS). His research was mainly responsible for the commercialization of this powerful method of IR spectroscopy and has been recognized already with the Bronze Medal of the CRNS in 1993 and with the prize of the physical chemistry division of the French chemical society (SCF: Societé Chimique de France) in 2001.

The advantage of the PM-IRRAS technique is that it exploits the different adsorption behavior of p- and s-polarized light at large angles of incidence. Ultra-thin layers deposited on metal surfaces interact exclusively with p-polarized light, therefore, through modulation of s- and p-polarization two attenuated total reflection (ATR) spectra can be recorded simultaneously and compared against each other. Another important advantage compared to the classical method used so far is that recording a reference spectrum is no longer needed. PM-IRRAS proved to be useful not only for the characterization of ultra-thin films but also for adsorbed molecules in the gas phase and organic (sub)-monolayers deposited on reflecting surfaces.
