The main part of the activities are related to laboratory astrophysics in order to provide molecular data on **polycyclic aromatic hydrocarbons (PAHs)** and related species **of astrophysical interest**, as well as tools to analyze astronomical data.
More specifically, we cover the following topics:

** * Spectroscopy**

- Evolution of infrared spectra with temperature. Simulations of the astronomical Aromatic IR Bands.

- UV/visible spectroscopy. Link with the interstellar extinction curve.

**  * Photophysics in isolated environments**

- UV-VUV photodissociation and photoionization.

- Competition with radiative cooling.

- Model of the evolution of PAHs in astrophysical environments.

**  * Mass spectrometry analysis**

- Characterization of the molecular content of cosmic dust analogues and meteoritic samples.
