The "Service de Chimie quantique et Photophysique" (previously "Service de Chimie Physique Moléculaire") is active in the field of physical chemistry. The research focuses on the internal structure of atoms and molecules and their related reactivity. We interrogate species using light and perform high resolution spectroscopic experiments with Fourier transform interferometers and lasers. We simultaneously calculate their properties using computers with ab initio time dependent and independent methods. We are most concerned by the role the species we investigate play in Earth’s atmospheric processes, and in other planetary and stellar atmospheres as well as in the interstellar space. Besides the development of state-of-the-art experimental and theoretical investigation means in the laboratory, we participate to remote sensing satellite missions and perform ground based validation measurements. Theoretical modeling results from both our laboratory and remote sensing activities.

Our research activities are detailed under the following three main themes:

• Experimental Molecular Chemical Physics
• Quantum Chemistry and Atomic Physics
• Spectroscopy of the Atmosphere

Results of this research are published in peer-reviewed international journals.

Our dedicated teaching concerns chemical physics (BA) and (MA) quantum chemistry, atomic and molecular physics, atomic and molecular ab initio calculations, photophysics, reactivity at the microscopic level, molecular vibration and rotation, high resolution experimental and quantitative spectroscopy, atmospheric chemistry and physics. It addresses mainly, but not exclusively, students from the section of chemistry and physics in the Faculty of Sciences and from the section of Physics in the Faculty of Applied Sciences.
