Structural determination

3CACA1 Structural determination Materials and Chemistry S9
Lessons : 15 h TD : 0 h TP : 0 h Project : 0 h Total : 15 h
Co-ordinator : Stephane Perrio
Prerequisite
Previous courses dedicated to NMR spectroscopy
– 1st year (1M1AC4) : Structural analysis of molecules
– 2nd year (2C1AD4) : Molecular spectroscopy
Course Objectives
Addressing 1D and 2D NMR from the perspective of the organic chemist and not the spectroscopy specialist (the minimum of theory) – A large part of this course consists in the analysis of spectra, with in mind to describe correctly a compound in an experimental section. Determine a complex structure from a set of NMR data and assign all signals. Becoming familiar with modern and routine NMR techniques.
Syllabus
1 - Revision of the crucial knowledge in 1H and 13C NMR (chemical/magnetical équivalence, influence of symmetry elements, nomenclature of coupled spin systems, multiplet interpretation). 2 - 2D NMR (1H COSY, HMQC, HMBC, INADEQUATE, TOCSY, NOESY, HOESY, DOSY). 3 - 19F NMR. 4 - 31P NMR. 5 - Analytic approach for a full characterization of a compound, using a set of NMR spectra.
Practical work (TD or TP)
Some spectra are analyzed individually during the courses, or prepared as homework. Past exams provided.
Acquired skills
Knowledge of the modern and routine NMR (1D and 2D) experiments. Application to the full characterization of structurally diversified organic compounds. Interpretation and description of the spectra (experimental section, publication).
