Communication skills: the students will be able to use a suitable chemical vocabulary in relation to the topics described in the course and to write report on the result obtained from the application of these techniques. He will develop the ability in making judgements and autonomously deepen the arguments treated in the course.

Content of Inorganic and Physical Chemistry courses.

Lectures integrated with some exercises in class and/or experiments on spectrometers and related discussion and data analysis. The optical and magnetic properties of the complexes of f elements and their use in biomedicine are the object of specific seminars and left to an independent learning process by students.

The main topics of the course will be discussed collectively in the classroom and applied directly during exercises in class (interpretation of NMR spectra) and on spectrometers.

Written exam consisting of: 6 open questions on the most relevant topics (18 points); assignment of 1H and 13C spectra of an molecule based on 1D and 2D experimental data (4 points). The results of the exam clarify the understanding of theoretical concepts, the ability to use them to solve problems of medium difficulty, the skill of making judgements and the knowledge of an appropriate technical-scientific language. The student will pass the exam with the knowledge of the basic concepts (13/30) and will get the highest grade demonstrating all the listed abilities/capacities. Additional points relative to the laboratory report will be added to the score achieved with the written exam (see Syllabus of the joined course).

Spectroscopic methods based on magnetic resonance for the study of molecular structure and dynamic processes. First- and second-order NMR spectra. Relaxation times: definition, measures and mechanisms. Modern techniques: 1) double resonance: broadband decoupling (gated and off-resonance); 2) NOE: principles and applications; 3) INEPT and DEPT sequences. 2D NMR: general and homo- and heteronuclear experiments (COSY, EXSY, NOESY, HMQC, HMBC). Dynamic NMR: general information, line-shape analysis, kinetic parameters, applications. NMR and the Periodic Table: applications in inorganic chemistry. Solid state NMR: general principles and applications. NMR of paramagnetic systems: metal ions, complexes and conjugates to macromolecules. Relaxometric techniques and fast- field cycling relaxometry. Principles of MRI and use of metal systems as contrast agents. Organometallic chemistry: carbonyls, metallocenes, metal clusters; characteristic reactions. Catalysis: metathesis and hydrogenation of alkenes, hydroformylation, oxidation, formation of C-C bonds, oligomerizations and polymerizations. The coordination chemistry of the f elements: orbitals, oxidation states, occurrence and recovery; optical and magnetic properties; coordination and organometallic compounds.

Knowledge and understanding: knowledge of the most common NMR techniques and their applications; knowledge of the principles useful to assign and/or predict 1H and 13C NMR spectra of organic molecules and simple inorganic molecules. Familiarity with the main chemical characteristics of organometallic compounds of d and f blocks and their applications in organic synthesis and industrial catalysis.
Applying knowledge and understanding: ability to apply the theory to the interpretation of NMR spectra (ability to assign and/or predict 1H and 13C NMR spectra of organic molecules and simple inorganic molecules), to the analysis of the 1H and 13C relaxation times and to explanation of temperature-dependent phenomena. Ability to use knowledge of structure and bonding in organometallic compounds to interpret their role in catalysis.
Making judgements: skill to critically evaluate the concepts learnt.
Communication skills: ability to use appropriate scientific language in answering questions and analyzing spectral data; achievement of a suitable scientific language to communicate in a correct, concise and clear manner.
Learning skills: ability to use the teaching material for a critical study that allows the possibility of an autonomous acquisition of further knowledge in the field of NMR spectroscopy and the most advanced applications of inorganic chemistry.
