Structural Chemistry
A.Y. 2023/2024
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.
