The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.

Content

Topics covered:

- Symmetry Elements

- Crystal lattice

- Point Groups

- Space groups

- Use of the International Tables for Crystallography

- Principles of diffraction, reciprocal space

- Intensity diffracted by a crystal

- Single-crystal diffraction, powder diffraction

- Experimental methods and instruments

- Information obtained from the diffraction

- Introduction to structural chemistry, contribution of crystallography to chemistry knowledge

Exercises:

  1. Point groups
  2. Lattice. Planar groups. Glide plane
  3. Space groups
  4. Practical exercises in the laboratory: single crystal diffraction, powder diffraction
  5. Description and comparison of crystal structures. Structure types
Teaching methods

The course is taught with the use of PowerPoint slides, available at Moodle. The lecture course also includes demonstration software and the use of interactive material. Exercises are provided to facilitate the understanding.

Evaluation methods

oral exam with a written preparation. It includes two theoretical questions: one with and one without a written preparation (15 points). The practical part is examined by the engineer, Dr. Koen Robeyns, and is evaluated with a maximum of 5 points. One more point students can get for the creative home work (the task is given).

Other information

Skills to be acquired:

- understanding the symmetry and in particular of the molecular symmetry

- understanding the foundations of modern crystallographic analysis and results they deliver
