Course objectives
Basic observables of the NMR spectra, such as shielding constants and chemical shifts, scalar couplings, and relaxation times, are discussed in this course. Influence of chemical and physical factors, structural parametrs, and effects of chemical exchange on their values are emphasized. Practical examples and problems are shown from the area of multinuclear NMR spectroscopy of inorganic compounds.
Syllabus
  • 1. Historical background. Basic concepts: nuclear spin, magnetic moment, magnetogyric ratio, natural abundance, magnetization, population, Larmor frequency.

    2. Shielding constants, diamagnetic and paramagnetic shielding, Ramsey formula. Local and nonlocal effects. Chemical shifts, referencing. Ranges of chemical shifts.

    3. Parameters influencing the magnitude of shielding constant: oxidation state, coordination number, charge, symmetry, HOMO-LUMO gap, electronegativity, normal and inverse halogen series, nephelauxetic and spectrochemical series.

    4. Correlation of chemical shifts with bond lengths and angles, UV maxima, IR force constants, Hammet sigma constants.

    5. Chemical shift effects: isotope effects, SIIS, magnetic anisotropy of chemical groups, temperature, solvent, ASIS.

    6. Satellite signals, isotopomers, abundance calculations.

    7. Chemical equivalence and molecular symmetry. Prochiral and C2 groups. Homotopic, enantiotopic, diastereotopic, and heterotopic nuclei. Chiral solvents, shift reagents.

    8. Dipolar coupling. Solid state NMR spectroscopy.

    9. Scalar coupling. Coupling constants, Dirac model, Pople-Santry formula, reduced coupling constant. Coupling constant effects: s-character, hybridization, electronegativity, coordination number, bond angles, dihedral angles, Karplus equation.

    10. Multiplet construction. Spin system notation. Simple spin systems: AB, ABX, AA'X, AA'XX'. Spectral simulation.

    11. Relaxation. Relaxation times T1 a T2. Correlation time. Extreme narrowing limit. Inversion Recovery and Spin Echo methods.

    12. Relaxation mechanisms: dipolar, chemical shift anisotropy, spin rotation, scalar, quadrupolar, paramagnetic. NOE.

    13. Dynamic NMR spectroscopy. Chemical exchange. Degenerate and nondegenerate systems. Dynamic NMR spectra simulation.
