- X-ray diffraction.
Theory: introduction to crystallography. Reticular theory. Crystalline structures. Miller index. Geometry Bragg-Brentano. X-ray diffraction.
PC practice. Use of the CaRIne Crystallography Program for the study of crystalline structures and obtaining of powder diffraction diagrams. Crystallochemical analysisof structures (link distances, coordination number, etc.). Use of the PDF database (Powder Diffraction File), of the ICDD (International Center for Diffraction Data) for the identification of phases
Laboratory practice. Use of a teaching diffractometer set-up. Acquisition of monocrystalline diffraction spectra. Analysis of the data. Determination of cell parameters, indexation of peaks.
The course is divided into 21 hours of theory, 6 hours of problems in the classroom and 40 hours of practice (laboratory and online).
Theory: the physicochemical concepts that will be used in the different experimental techniques will be introduced. Exercises will be carried out that will allow a better understanding of the phenomena involved as well as introduce data processing and interpretation.
Classroom Excercices: CaRIne Crystallography free software for solving problems on crystal structures and diffraction. The students will bring their own computer.
Practices: The practical sessions will be carried out in groups or individually to achieve the learning results of the subject.
The student will find in the Moodle classroom of the subject the notes in pdf format, the distribution by groups, the calendar and the scripts of the practices. For the perfect use of the practical hours, the student will have to review the corresponding theory, the practical script and the corresponding complementary documentation (articles, videos, etc.) before each practical session.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

The competences of this subject will be evaluated through different ways, each one with a certain weight in the final grade.
- Theoretical exam: a test will be carried out with a total weight of 25% of the final grade, with a minimum grade of 3.5 to pass the subject. Students will have a second chance to pass this minimum, and therefore be able to pass the subject, with a recovery exam.
- Practical exam: an individual session will be held for each student to evaluate the knowledge acquired regarding the different practices carried out, mandatory and which will have a total weight of 20% of the final grade.
- Deliveries (reports, problems). An evaluation will be carried out for each of the deliveries with the weight specified in the table of evaluation activities.
Note that before some of the proposed activities the student will have to complete an individual and mandatory test. Failure to do so on time will mean a penalty of 0.5 out of 10 points for the corresponding activity. In some cases, it will be proposed to carry out complementary activities prior to the delivery of the practice report.
Attendance at all practices and their completion is mandatory. There is no second evaluation of practical activities.
To pass the course you must have a final grade equal to or greater than 5, as long as you have obtained a minimum of 3.5 on the theoretical exam.
