Title: *Frontiers of synchrotron-based UV Resonance Raman spectroscopy 
for exploring molecular systems

*
Abstract:
Raman spectroscopy is a non-destructive experimental technique widely 
implemented in the laboratories for the molecular characterization of 
several kind of systems, including condensed matter, liquids, gels, 
aqueous solutions, polymers and bio-macromolecules, through the 
investigation of their vibrational dynamics. Thanks to the resonance 
effect, UV Resonance Raman (UVRR) spectroscopy offers several advantages 
with respect to conventional visible Raman technique, such as the 
significant increment of the detection limit and the selectivity needed 
to incisively monitor specific chromospheres within the sample. This 
determines the usefulness of UVRR spectroscopy as highly sensitive and 
selective spectral probe for exploring the structure and dynamics of 
complex molecular systems. However, the full exploitation of UVRR has so 
far been limited by the lack of extended and tuneable excitation sources 
in the UV range that allow to finely approach the resonance conditions 
of specific targeted molecular groups.  In this seminar, we would like 
to give an overview on the opportunities offered by the unique in the 
world UVRR setup working with the synchrotron radiation (SR) source 
available at the BL10.2-IUVS beamline (Elettra synchrotron facility, 
Trieste, Italy). The SR-based UVRR set-up at Elettra enables to perform 
UVRR experiments with a fine tuneable source in the range of excitation 
wavelengths 200-270 nm, resulting in an innovative spectroscopy facility 
for approaching open issues in physics, chemistry, materials and life 
sciences. Selected case studies will be discussed in order to show the 
useful of SR-based UVRR method and the areas of interactions with other 
research interests.
