Structural Chemistry
A.Y. 2024/2025
Learning objectives
The students will be provided the tools to describe the symmetries present in a crystal and in a lattice, the criteria for the classification in the crystalline classes and space groups and the knowledge for the interpretation and use of the International Tables of Crystallography. The students will learn the basic concepts of the theory of diffraction and of other synchrotron radiation and neutron advanced techniques for the characterization of the crystalline materials.
Expected learning outcomes
The students will be able to apply the knowledge of the crystal symmetry for description of crystalline material through the symbols of crystalline classes and space groups and to correctly interpret and use the International Tables of Crystallography. Students will also gain a useful knowledge on the theoretical principles of diffraction and of other synchrotron radiation and neutron spectroscopies for the characterization of crystalline materials.

Assessment methods and Criteria
The assessment of learning take place through an oral examination. The final grade is expressed in 30/30 were 18/30 represents the minimum. Students attending the course will be given the opportunity to take two partial exams (partial and end-of-semester). The final mark will be determined by the mean of the two partial evaluations that must both be higher or at least equal to 18/30. During each academic year, a number of at least 6 exams will be set, in the ordinary exam sessions.
The exam consists of a series of open-ended questions designed to ascertain the level of knowledge and understanding of the course contents and the ability to connect the different topics. The ability to express oneself correctly with proper scientific cognition and the clarity and thoroughness of exposition will also be assessed.
