Molecules are of many types, from small to large and from light to heavy. Their infrared signature are quite different, revealing their own characteristics.

 I am interested to study the infrared spectra of small and linear molecules.   Acetylene is a prototype molecule in this field since it contains only four atoms and the quantum mechanical theory could easily used to describe its IR spectra.  Infrared satellite detection shown that acetylene is present in many regions of our universe (Planets, Carbon rich stars, Comets…). Furthermore, acetylene is a precursor of chemical reactions and seems to have an important role in the formation of organic polyatomic molecules (hydrocarbons, cyanoapolyynes, polymers, prebiotic molecules…).

In my thesis I was interested by the analysis of the vibration-rotation spectra of ¹²C₂H₂ and ¹²CH¹³CH isotopologues in their ground electronic states.  We aimed to build a global model to deal with all vibration-rotation levels up to about 9000 cm^-1 vibrational excitation.  Different applications have been emerged from this global model, from high resolution spectroscopy analysis to intramolecular dynamics.
