SPECTROSCOPY AND PRACTICE

The course is part of the core educational activities of Bachelor's Degree in Science and Technologies for Cultural Heritage (CT60), and it allows to acquire the basic knowledge and the understanding of the fundamentals of ultraviolet-visible, infrared, and Raman spectroscopy. The knowledge of spectroscopy are crucial for CT60 graduates because in the field of cultural heritage almost all the diagnostic techniques are spectroscopic.

The expected learning outcomes are the knowledge and understanding of the concepts presented during the lessons and the ability to use them to solve theoretical and practical problems. Furthermore, students must be able to communicate the knowledge learned and the results of their applications using appropriate terminology.

The prerequisites of the course are the training objectives of Organic Chemistry. In particular, students should know nomenclature, structure and properties of the main classes of organic compounds.

Electromagnetic radiation and the electromagnetic spectrum. Energy states of a free molecule and population levels. ultraviolet-visible (Uv-Vis) spectroscopy: introduction. Examples of Uv-Vis spectra. Instrumentation. Lambert-Beer Law. Types of electronic transitions. Chromophores and auxochromes. The characteristic absorption bands of some classes of organic compounds. Fluorescence and phosphorescence. Jablonski diagram. Infrared (IR) spectroscopy: introduction. The vibration of diatomic molecules, the harmonic oscillator model and the anharmonicity. The vibrations of polyatomic molecules: normal modes, vibrational transitions and corresponding absorption bands. Fermi resonance. Instrumentation and sample handling. General considerations about infrared spectra and absorption bands. Interpretation of infrared spectra. Characteristic IR absorption bands of some classes of organic compounds. Exercises on the interpretation of infrared spectra. Infrared spectra of some materials used in art and art conservation. Infrared reflection spectroscopy. Raman spectroscopy: introduction and basic concepts. Instrumentation. Raman versus Infrared Spectroscopy. Examples of Raman spectra. Applications of Raman spectroscopy to cultural heritage.

The learning verification method consists in a oral test.

The examination consists of a series of questions concerning the contents of the course. Students must demonstrate the learning of the topics covered and the ability to expose them in a formal manner. The examination lasts about 40 minutes.

Teaching is organized in lectures, including problem-solving exercises.

In the "Moodle" platform of the University there are all the slides projected during the lessons.
