Reference texts
The course slides are available for students. To learn more about the topics covered during the lessons, I recommend: Peter William Atkins & Julio de Paula, Elementi di chimica fisica, Zanichelli, 2018.
Educational objectives
The main objective of the course is to transmit the following knowledge to the student:
- fundamental principles of atomic structure and composition of matter;
- relationships between electronic configuration, the periodic table, and the chemical and physical properties of elements;
- nature of chemical bonding, molecular geometry, and the main intermolecular interactions
- use of spectroscopic techniques for the determination of molecular properties.
- main applications of photochromic materials.

The teaching will allow the student to acquire the following skills:
- correlate atomic and molecular structure with the macroscopic properties of matter;
- understand the role of chemical bonds and intermolecular interactions in determining the structure and behavior of materials.
- use the IR and UV-Vis spectroscopic techniques in the characterization of the materials used in optics.
- identify the applicative potential of photochromic systems based on their chemical-physical properties.
Prerequisites
In order to understand and be able to apply the spectroscopic techniques described in the course, it is necessary to have basic knowledge of mathematics and physics.
Teaching methods
The course consists of lectures covering all the topics of the course for a total of 42 hours.
Other information
The teacher is available to discuss with the students via email or by scheduling a meeting on the Microsoft Teams platform.
Learning verification modality
The exam consists in an oral test lasting about 30 minutes aimed at ascertaining the level of knowledge and understanding achieved by the student on the contents listed in the program. The oral test will also allow to verify the students' communication skills and their language properties.

Extended program
Rudiments of general chemistry: atomic theories, the quantum atom, electronic configurations, the periodic table, and chemical bonds. Molecular geometry, intermolecular interactions, and properties of solutions. Optical phenomena and introduction to spectroscopy: electromagnetic spectrum, light-matter interaction, energy quantization, transitions, Boltzmann distribution. Spectrometers: sources (lamps and lasers), monochromators, and detectors. The spectra: lines and bands, the amplitude and intensity of the spectral lines (or bands), the Lambert-Beer law. Rotational spectroscopy. Vibrational spectroscopy: vibrational modes, vibrational transitions, IR spectrophotometers, mid-IR spectra. Electron spectroscopy: the Franck-Condon principle, the spectra of polyatomic molecules, solvatochromism. Photochemistry and photophysics: photochromic materials, the evolution of excited electronic states, radiative transitions (fluorescence and phosphorescence), non-radiative transitions.
