There are many advantages in the use of synchrotron radiation (SR) compared to conventional “laboratory” source for the characterization of liquid systems and materials. First of all, the high brightness, wavelength-controlled and tunable emission of SR allows to tune in a very efficient way cross sections and atomic edges of the systems under investigation. The SR emission is a coherent and multiply polarized radiation that can be used for probing dichroic effects and bonding orientation. Finally, there are a great variety of SR-based spectroscopies that provide elemental, chemical and magnetic information and a large variety of imaging contrasts based on photon absorption, scattering or spectroscopic feature. The purpose of this course is to give an overview of the SR-based techniques useful for the characterization of liquid systems, soft matter and materials. Moreover, basic information helpful to successfully applying for obtaining beamtime at SR facilities will be provided.
The following topics will be presented and discussed:
⦁ SR production and operation of SR sources;
⦁ SR-based spectroscopic techniques: Infrared Absorption and UV Resonance Raman scattering;
⦁ Selected case studies on different systems including, biological systems, ionic liquids, materials of interest for cultural heritage;
⦁ Writing a proposal to perform experiments at SR facilities.
