IUVS: Inelastic Ultraviolet Scattering Lab
Welcome to the Inelastic UltraViolet Scattering LaboratoryThe IUVS (Inelastic Ultraviolet Scattering) Laboratory is a user facility for UV Resonance Raman scattering (UVRR) spectroscopy at Elettra with tunable laser sources in the range between 150 and 400 nm. Our mission is to develop and offer to users advanced UVRR setup exploiting both fixed UV laser sources (at 213, 224, 248 and 266 nm) and fully tunable ps- and ns- laser sources with emission in the FUV-DUV-near UV range (150-315 nm, 350-475 nm). Our in-house research projects include the application of UVRR spectroscopy in relevant scientific fields, such as chemical-physics of water and liquids, characterization of polymers and gels, investigation of biological molecules such as proteins, peptides and DNA, carbon-related materials, nanostructures and materials, supramolecular chemistry, forensic science. |

The inelastic scattering phenomenon known as the Raman effect consists in the exchange of a quantum vibrational energy occurring when a monochromatic light illuminates a molecular system. The shift in the photon energy between incident and inelastically scattered light corresponds to a vibrational frequency due to the excitation/deactivation of molecular vibrations.
The Resonance Raman effect offers the possibility to overcome some limitations affecting non-resonance conventional Raman spectroscopy, by dramatically improving the selectivity and sensitivity. If the incident light frequency is in correspondence (or close) of any absorption band associated with an excited electronic state, the same vibrational transition takes place upon the so-called resonance Raman (RR) scattering. Upon this condition, the intensity of the vibrational modes whose motions are coupled to the driven motion of the electronic transition are selectively enhanced in the Raman spectrum

Proposal SubmissionWe invite users and collabrators to discuss thier proposals with the beamline local contacts well in advance before the submission deadline. This is crucial for a careful assesment of the experiment feasibility and may lead to improvements in the proposed experimental plan. In a restricted number of cases, when doubts arise about the suitability of your samples (sample absorption etc), it may be possible for you to arrange a test. Our website provides a wealth of informaiton on experiment feasibilty and proposal submission. For more info, please vist the IUVS Users section. |
