research

My research is in the field of high resolution spectroscopy of isolated molecules with a double objective:
- understand the structure and internal motions of molecular systems
- bring information to other disciplines at the interface with molecular physics, astrophysics, planet atmospheres and biology.
Two classes of molecules are studied:
1) molecules containing large amplitude motions like internal rotation of methyl groups (acetaldehyde, acetic acid, acetamide, methyl formate, methyl acetate) or inversion (NH3). We wrote our home-made codes (BELGI-Cs, BELGI-C1, BELGI-2Tops-Cs ) to calculate energy levels,line frequencies and intensities and to fit microwave, (sub)millimeter, infrared data at experimental accuracy.

2) molecules belonging to the C3v symmetry (NH3, PH3, CH3Br, CH3D). For those molecules we also can calculate and fit their infrared spectral data within experimental accuracy which can then be used to support the analysis of planetary spectra
