Learning objectives

The Course of Applied Spectroscopy aims to provide students with the basic tools of quantum mechanics necessary to understand and use the spectroscopic methodologies of interest in chemistry

 D1 - Knowledge and ability to understand:
At the end of the course the student is expected to be able to know the fundamental principles of the interaction between electromagnetic radiation and molecules,
He should know the concepts of molecular spectroscopy; understand the mathematical language necessary for the description of time-dependent phenomena and of the radiation-matter interaction, understand the problems associated with advanced optical spectroscopy experiments.

D2 - Ability to apply knowledge and understanding
The student will have the ability to understand the relevant scientific literature, and to understand the relationships between molecular structure, electronic structure and spectroscopic properties; The student will be able to choose and use the main optical spectroscopy techniques to analyze and characterize the properties of molecular systems.

 D3 - Autonomy of judgment
The student will be able to independently analyze and evaluate the choice of the best spectroscopic techniques to be used for the characterization of materials and molecular systems. He will be able to interpret the experimental results.

D4 - Communication skills
The student will be able to communicate and comment on issues related to optical spectroscopy and its applications also in an interdisciplinary way with physicists,
biologists and materials scientists.

D5 -
The student will be able to deepen and extend their knowledge
using bibliographic resources, scientific articles and reviews on more specialized subjects.

Teaching methods

The course of 48 CFU will use lectures and heuristic lessons for the first part of the course.
In the second part of the course we will mainly spend our time in the lab to extend and apply concepts in optica spectroscopy.

Assessment methods and criteria

Oral exam to evaluate knowledge, comprehension skills and critical understanding, The exam is divided into two questions, one on a specific topic chosen by the student that must be deepened and organized by the student himself and a second one on a more general topic concerning the basics of optical spectroscopy.
