Séminaire "Physique Moléculaire" : Clément Lauzin (Université Catholique de Louvain)

Clément Lauzin de l'Institut de la Matière Condensée et des Nanosciences, Université Catholique de Louvain, Louvain-la-Neuve, Belgique, donnera un séminaire intitulé "Development of high-resolution spectrometers to study fragile molecules". Rendez-vous ce Jeudi 12 mars à 10h30 en salle 120E.


Our group of research is building and improving three spectrometers to achieve high resolution spectroscopy of isolated molecules, molecular complexes and ionic species. This talk will be focused on these instruments and on first results obtained with it. In particular, we will consider the spectra of H2O-CO2 and H2O-N2 van der Waals complexes recorded by cavity ringdown spectroscopy in the 2OH range and the spectrum of the \(A^2 \Sigma^+ - B^2 \Pi^+\) electronic transition of N2O+ recorded by action (photodissociation) spectroscopy. Finally, the third spectrometer combining a Fourier transform spectrometer, an optical cavity and a broadband light source will be briefly presented.
