Photosciences: Light plays a role in many physical and chemical processes; it is also an exceptional tool in the investigation of matter. Photo-scientists within laboratories of IRAMIS study the interaction between light and matter as a fundamental process and an analysis tool. Lasers: Photoscience is becoming increasingly important due to the rise of ultra-short light pulses, often ultra-intense.
A chemical reaction depends not only of atoms and molecules involved but also of their short range environment. Understanding a chemical reaction demands a fundamental approach taking into account both temporal and spatial features. Therefore, IRAMIS implements with lasers, time-resolved spectroscopies in the range from femtosecond to the millisecond, to study the dynamics of molecular systems, like for example DNA biomolecules, or chromophore molecules for photovoltaics.
