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:
- use of spectroscopic techniques for the determination of molecular properties.
- main methods of structural investigation and chemical-physical characterization of molecular systems of interest in optics.
The teaching will allow the student to acquire the following skills:
- use the IR and UV-Vis spectroscopic techniques in the characterization of the materials used in optics.
- identify the applicative potential of molecular systems of interest in optics 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.

- Rudiments of chemistry: atomic theories, the quantum atom, electronic configurations, the periodic table, and chemical bonds. 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. Time-resolved spectroscopy: transient absorption and fluorescence up-conversion. Two-photon absorption.
