Abstract
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 parameters, 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.
Learning outcomes
Students will learn in this course:
To find symmetry elements in molecules and predict expected number of signals in spectra of the NMR active nuclei present in the molecule.
To estimate the magnitude of chemical shift in spectra of nuclei as a function of molecular structure and electronic environment.
To calculate the expected multiplicity of signals of measured nuclei in interaction with neighbouring active nuclei.
To estimate the magnitude of scalar coupling constants in dependence on bonding parameters and structural features of molecules.
To judge nuclear, electronic, and structural influence on relaxation rates of nuclei.
To establish influence of chemical and physical factors and structural parameters on chemical exchange and its effect on number and shape of signals in NMR spectra.
Key topics
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.

Approaches, practices, and methods used in teaching
The course consists of 14 lectures of 50 minutes each. Course materials, such as lecture slides, supplementary articles, tables, are available to students in the Information System of Masaryk University. Additional relevant lectures given by visiting professors under INNOLEC program are part of the course in particular cases.
Method of verifying learning outcomes and course completion requirements
There are 3 graded homeworks during the semester. At the end of the course every student will give a short presentation on a selected topic concerning NMR spectroscopy. Written final exam worth 100 pts, minimum 50 pts to pass. Grading weights: final test 75%, homeworks 15%, presentation 10%.
