Learning outcomes
The teaching aims at supplying knowledge on FT-NMR techniques through the phenomenologic study of the involved pulse sequences. At the end of the teaching, the student must be able to choose and execute the most suitable NMR experiment for the attainment of the required informations.
Course contents
The pulse experiment: magnetization and nuclear precession, FID, relaxation, signal sampling. Natural and digital resolution. Measuring of relaxation times T1 and T2 trough inversion-recovery and spin-echo sequences. C13 multiplicity: APT and DEPT experiments. Diamagnetic and paramagnetic shield constant of non-hydrogen nuclei and effects on the chemical shift. Connections through space: dipole-dipole relaxation mechanism and relaxation paths. Homo and heteronuclear NOE. Internuclear distance effect. Connections through chemical exchange: fast and slow exchanges. Hydrogen bonds. Coupling and decoupling. Chemical and magnetic equivalence. Homo and heteronuclear bidimensional techniques. More common heteronuclei. Solid state NMR.
