Learning outcomes
After completing this unit, the student should be able to sketch a plan for the analysis of a Cultural Heritage sample, he should be familiar with the sample preparation . The student should also know the modern spectroscopic techniques and be able to interpret the spectra obtained from the analysis of the samples.
Course contents
The aim of the course is (i) to provide the general theoretical
basis needed for a proper understanding of spectroscopical
phenomena and (ii) to discuss various spectroscopic technique
important for the study of Cultural Heritage materials, introducing
methodologies, range of applications and examples. The course is
organized in two modules that will be taught by Prof. F.
Tamassia (A) Prof. C. Zannoni (B). The course will cover the
following topics:
-Theoretical background for the comprehension of spectroscopic
experiments: Interaction radiation-matter. Harmonic oscillator as a
quantum model. Molecular vibrations. Lasers.
-Infrared and Raman spectroscopy. Fourier transform spectroscopy. Examples of applications to materials in cultural heritage
(B)- Fluorescence spectroscopy. Elements of the technique. Applications of fluorescence mapping to investigate organic depositions on works of art (e.g. paintings)
- Xray techniques. Introduction to Xray sources (including synchrotron radiation). Powder and surface micro-diffraction (examples of pigment identifications, identification of ceramics or porcelain components). Extended X-ray Absorption Fine Structure (EXAFS) . XRF. Examples
-Neutron scattering techniques neutron sources and properties.
applications
- Spectroscopic investigations of nanoparticle based cultural
heritage materials and techniques (e.g. lustre, purple of
Cassius).
- Magnetic Resonance Techniques: Introduction to NMR. Portable
NMR- MOUSE (mobile universal surface explorer)- applications
to porous materials
-Electron Spin Resonance (ESR). Introduction to the technique. Some relevant applications (e.g. fossile dating)
Readings/Bibliography
Single chapters of several books will be
recommended.
A copy of the lecture slides will be given to the students.
Teaching methods
All subjects are discussed in detail during the lectures. Students are invited to participate with questions and comments.
