Summary
On the basis of fundamental knowledges necessary for a good understanding of the one-dimensional 1H and 13C Nuclear Magnetic Resonance (NMR) spectra, being able to determine the structures and the properties (chemical shifts and coupling constants) of small organic molecules at liquid state.
Educational goals
Knowledge: Knowing the basics theory of 1D NMR for 1H and 13C nuclei, Skills: - Interpretation of 1H and 13C NMR spectra of small organic molecules (solution, liquid state), - Identification of groups of chemically and magnetically equivalent nuclei, - Recognition of homotopic, enantiotopic and diasterotopic nucleii, - Analysis of first-order and second-order spin-spin coupling systems, - Determination of J coupling constants for first-order coupling systems, - Analysis of nuclei chemical shifts in terms of surrounding in the molecule: magnetic anisotropy and electronic (inductive and mesomeric) effects.
