PERIOD: MAY This course is aimed at providing the theoretical bases of the main spectroscopic techniques (IR, Raman, UV-vis, XPS) and at describing their application to the characterization of materials. For each technique, practical activities in small groups are planned on the analysis and interpretation of real spectra provided. The course also includes principles of multivariate data analysis.

Overview of spectroscopy techniques: Light-matter interaction Principles of IR and Raman spectroscopies MIR and NIR – examples of applications FTIR and FTRaman Basics of FTIR and Raman hardware Gas Phase IR spectroscopy: principles, applications and examples Practical activity in small groups: identifying an unknown gas mixture FTIR of condensed organic matter. Functional groups and fingerprint region Practical activity in small groups: identifying an unknown organic sample FTIR of inorganics and inorganic surfaces and interaction with gases Practical activity in small groups: IR spectroscopy as a tool to assess the surface functionalities of inorganic solids, both directly and by dosing probe molecules Raman: principle, examples and applications for both organic and inorganic materials Basics of Surface Enhanced Raman Scattering (SERS) and Tip Enhanced Raman Scattering (TERS) techniques Practical activity in small groups: Analysis an interpretation of Raman spectra for unknown samples UV-Visible spectroscopy: Principle and examples. Absorbance and diffuse reflectance methods applied to solutions, bulk and surfaces Practical activity in small groups: UV-Vis as a tool to assess electronic transitions occurring both in liquid phases and in solids X-ray Photoelectron Spectroscopy (XPS): Principle and examples on both organic and inorganic materials Practical activity in small groups: Analysis an interpretation of XPS Survey and High Resolution spectra for unknown samples Introduction to data treatment: multivariate analysis, methods and software
