Molecular Spectroscopy

Electron Spectrosopies (ETS, DEAS)

Alberto Modelli

A complete picture of the electronic structure requires the knowledge of both the filled and the empty levels, equally important from the thoretical and the reactivity points of view. ETS is one of the most suitable means for measuring the energies of formation of gas-phase temporary anion states. DEAS reveals the presence of dissociative decay channels and the negative fragments produced. Our ETS apparatus is one of the few existing in the world.

Rotational spectroscopy in the millimetre and sub-millimetre wave regions

Claudio Degli Esposti, Luca Dore, Cristina Puzzarini

Challenges in high resolution molecular spectroscopy, spectrum observation, and correct interpretation of results are never obvious or immediate. We are dealing with rotational spectroscopy of ions, radicals, molecules and isotopologists of astrophysical and astrochemical interest; spectroscopic characterization of bulding blocks of biomolecules and clusters of atmospheric, chemical and biological interest; characterization of molecular structures and determination of force fields; Analysis of the line broadening of atmospheric species; sub-Doppler spectroscopy with the Lamb-dip technique.

Free Jet Molecular Spectroscopy

Sonia Melandri, Assimo Maris, Luca Evangelisti

The group's research activity concerns the study of the properties of molecules and weakly-bond molecular complexes, such as structure, conformation, tautomerism, and the intra-inter-molecular interactions that characterize them, using the supersonic jet cooled rotational spectroscopy technique. Moreover, the group designs, develops and assemble unique instruments (sometimes prototypes) in Italy. In the group several analytical strategies (i.e. semirigid and coupled hamiltonians) and modeling (flexible models, ab initio mechanics or DFT and electrostatic models) are also implemented.
