Spectroscopy of molecular complexes
Infrared spectroscopy of a molecular complex hosted in a helium droplet makes possible to explore the structure of a complexe as well as its interaction with an environment. The Goutellium experimental setup carry out this type of study with two highly interconnected goals:
The helium droplet is described as a superfluid medium, except when in contact with a molecular potential which induces its a partial structuration. Our Group is one of the very few in the world to address this issue. It conbines both experimental and numerical approches.
Vibronic Spectroscopy of ions
The Reaction Dynamics Group has largely contributed to the development of slow electron spectroscopy (SPES) which provides the vibrational structure of ions in the geometry of the ground state neutral molecule. This technique is an improvement of TPEPICO or TPES techniques. This activity is carried out on the SAPHIRS device installed on the DESIRS beamline of the SOLEIL Synchrotron. We participate to 4 scientific projects:
The simulation of structures and the thermodynamics of the complexes are critical infomations for the interpretation of experimental studies. This activity has several aspects:
