Course objectives
At the end of the course students should be able to understand NMR spectroscopy as one of the most important methods of structural analysis. Graduates are expected to be oriented in the structural analysis of natural products and organic compounds by using high-resolution NMR spectroscopy. The main emphasis is directed to interpreting the spectra and extracting the information from basic 2D spectra (COSY, NOESY, HSQC, HMBC).
Learning outcomes
Student will be able to:
- suggest 1D and 2D NMR experiments appropriate to solve particular structural problem;
- describe principles of individual NMR techniques;
- compare and highlight differences among individual NMR correlation experiments;
- explain meanings of basic NMR parameters;
- interpret multidimensional NMR spectra of moderately complicated organic molecules, natural compounds, and simple biomacromolecules.
Syllabus
  • 1. Basic aspects of NMR - introduction, methods of magnetic resonance, nuclear interactions, origin of NMR signal, chemical shift, spin-spin scalar coupling, examples, Fourier transformation - nuclear relaxation (inversion recovery), selective excitation, suppression of solvent signal, NOE; 2. Construction of spectrometers - magnets, probes, tubes, NMR-HPLC, NMR-MS; 3. Editation techniques - spin echo, APT - polarisation transfer, INEPT, DEPT; 4. Multidimensional NMR spectroscopy - homonuclear shift correlation - correlation spectroscopy (COSY) - multiple bond interactions (LR-COSY, Relayed COSY) - TOCSY; 5. Heteronuclear chemical shift correlation - single bond (HETCOR) - multiple bond (LR-HETCOR, COLOC); 6. Measurement of J couplings - J spectroscopy - other techniques - chemical shift correlations, time domain; 7. Dipolar interactions - selective NOE - 2D NOESY; 8. Multiple-quantum spectroscopy - MQF-COSY - INADEQUATE; 9. NMR spectroscopy of various nuclei - 15N, 31P, 77Se (19F, 29Si, , 111Cd and 113Cd, 117Sn and 119Sn, 125Te, 195Pt, and 207Pb); 10. Inverse-detected experiments - single bond (HMQC, HSQC) - multiple bond (HMBC, HSQC) - hybrid experiments (HMQC-TOCSY, HSQC-TOCSY, HSQC-NOESY; 11. Gradient assisted spectroscopy - homonuclear shift correlations - NOESY - inverse-detected heteronuclear shift correlations; 12. Indirect spin-spin coupling and direct dipolar interaction - information for structural interpretation - J couplings and dihedral angles - NOE and interatomic distances - input for molecular mechanics; 13. Practical aspects - scopes and limitations - probehead selection, logical structure of analysis, sensitivity of experiments; 14. Practical examples and interpretation
