Learning outcomes |
The curricular unit on spectroscopic methods aims to provide students with the theoretical and practical bases for advanced analysis methodologies using spectroscopic techniques. The different spectroscopic techniques will be compared and their potential will be highlighted by discussing their application in different analytical problems, selected as case studies. The student will acquire spectroscopic data at the atomic level, followed by the determination of spectral parameters and the interpretation of spectra in terms of the structure of molecules.

Teaching Methodologies and Assessment Criteria |
Theoretical, theoretical-practical and practical classes of a dynamic nature, involving 5 modules. Each module has a practical assignment carried out individually.
Final mark (NF)= 70% Final theoretical mark (NFT) + 30% Seminar mark
- You can improve your grade by taking the final exam for all the modules.
-Attendance at theoretical, theoretical-practical and practical classes is compulsory (you can only give 3 absences to the Curricular Unit). Failure to comply with the attendance percentages prevents the student from being assessed for the course unit, i.e. they have no attendance.
