SPECTROSCOPY

Understanding of the basic principles underlying the most common spectroscopic techniques with e.m. waves for the characterization of molecules and solids.

In reference to the Dublin Descriptors:

• Critical understanding of the most advanced developments of Modern Physics, both theoretical and experimental, and their interrelations, also across different subjects.

• Remarkable acquaintance with the scientific method, understanding of nature, and of the research in Physics.

• Ability to identify the essential elements in a phenomenon, in terms of orders of magnitude and approximation level, and being able to perform the required approximations.

• Ability to use analogy as a tool to apply known solutions to new problems (problem solving).

• Ability to discuss about advanced physical concepts, both in Italian and in English.

• Ability to access to specialized literature both in the specific field of one's expertise, and in closely related fields.

Lessons with several practical examples e visits to laboratories.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

• General principles on spectroscpies with electromagnetic waves.
• EM wave propagation, complex refractive index and Fresnel coefficients.
• Sources, monocromators and detectors.
• Vibrations in molecules and solids.
• Model dielectic functions.
• Absorption and emission in semiconductors and insulators.
• Light scattering.
• Spectroscopies with X-rays.

Verification of learning is carried out through an oral exam

The exam typically begins with a generic question on one of the spectroscopies from which to eventually draw inspiration for a more detailed analysis, in order to evaluate the level of depth of the topic.

In addition to the level of detail and critical capacity, the clarity and logic of the presentation will also contribute to the evaluation.
