Learning outcomes
The course concerns the main spectroscopic techniques for the identification of organic compounds, in particular organic materials.
Moreover, the aim of the course is to give a general basic knowledge of the spectroscopic techniques, which could be useful for the structural investigation of various classes of chemical compounds.Course contents
Introduction to the main spectroscopic techniques used for the identification of organic materials. Basic on principles and review on the main application fields.
The first part of the course concerns the Nuclear Magnetic Resonance (NMR):
- NMR principles
- Chemical shift and coupling constants
- Analysis of 1H NMR spectra
- Acquisition of 13C spectra and DEPT techniques
- Basic on heteronuclear NMR spectroscopy (31P, 29Si, 11B) and its use in analysis of inorganic materials
- Bidimensional NMR analysis
- Solid phase NMR
- Practical exercitations about NMR spectra of organic compounds, pigmants, antioxidants, luminescent materials.
In the second part of the course, the mass spectrometry will be studied, with particular attention to the mass techniques which allow the determination of high molecular weights:
- Electronic impact techniques
- Fragmentation analysis for the structural assignment of simple molecules
- Application of mass spectroscopy for the measurement of large molecular weights compounds: FAB and ESI techniques.
- Practical exercitations on different mass spectra.
The principles of the IR spectrofotometry will be reviewed.
Finally, practical exercitations on the spectrometers and compared analyses of IR, NMR, and MS spectra in order to acquire experience in identification of organic compounds will be integrate and complete the course.

Teaching methods
The lectures will be constituted of a former part with the purpose to furnish the fundamentals that will permit a more specifical part. Some practical exercitations will follow the theoretical part. The discussion with the student will be welcome.
Assessment methods
Identification of an unknown compound by analysis of its NMR, IR and Mass spectra. Discussion on the test results.
Teaching tools
The teacher will use informatic supports for the exposure of texts and images. The material projected will be put to disposition of the students. Practical exercitations will be made on instruments of the Faculty available for teaching purposes.
