Credits: 
4
Period: 
First Semester
Standard lectures hours: 
32
Detail of lecture’s hours: 
Lesson (32 hours)
Requirements: 

Quantum Mechanics is a standard prerequisite for this course.

Oral examination on both part A and B of the course (30 min). Four questions:
2 questions on the content of section 1 as in the course program.
2 questions on the content of sections 2-7 as in the course program.

The evaluation criteria will consider:
1) the completeness of the acquired knowledge.
2) ability to report critically about the advantages and limitations of the different techniques.
3) ability to indicate the more appropriate spectroscopy to be used in different scenarios.
4) the technical terminology used.

Molecular Quantum Mechanics, Peter W. Atkins, Ronald S. Friedman, Oxford University Press.
Lecture notes will be provided for the sections on the synchrotron light and UV, XAS-XES spectroscopies.
Slides showing examples of spectra obtained with the different techniques will be also provided.

Frontal lessons (32 hours): introduction and theoretical development of the topics, exemplified by means of typical cases.
During the lessons, students are often involved by means of questions to make them more engaged according to the basic principles of active learning in its most elementary way.
Part of the lessons will be dedicated to the analysis of literature spectra obtained through the different techniques seen in the course. The educational goal of the exercises is to provide practical tools for the analysis of spectra and, through discussion, to develop a modus cogitandi for students to assign a certain spectroscopic technique to the resolution of a problem.
