6. Structure determination of ribosomal proteins and development of new methods in biomolecular NMR
Abstract : This thesis concerns different areas of biomolecular nuclearmagnetic resonance spectroscopy (NMR). In the first part of thethesis a new formalism for simulations of NMR pulse sequencesis introduced. The formalism is derived both from classicalmechanics and quantum mechanics and is presented forhomonuclear and heteronuclear spin systems. READ MORE

7. Heterogeneous Materials - Diffusion, Laplace Spectrum, and Nuclear Magnetic Resonance
Abstract : In this thesis diffusion in heterogeneous materials is studied using spectral analysisof the Laplace operator. Relations to the effective diffusion constant and therelaxation rate of the time-dependent diffusion coefficient for porous systems arederived from the Laplace operator’s spectrum. READ MORE

8. Internal rotation in molecules : a nuclear magnetic resonance relaxation study
Abstract : In order to study the internal rotation of methyl-type groups in molecules, the carbon-13 nuclear magnetic resonance (NMR) spin-lattice relaxation times (T1) and nuclear Overhauser enhancement factors (n) are measured for some terpenes (borneol, camphor, isopinocampheol and α-pinene), for octafluorotoluene and for 1-methylnaphtalene. In addition, deuterium NMR T1 data are presented for 1-methylnaphtalene-d10. READ MORE

9. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties
Abstract : This thesis discusses several different methods offered by solution and solid state nuclear magnetic resonance for investigation of host-guest complexes and their constituents. The presented methods were used especially (but not exclusively) to address rotational dynamics of the bound guest in different molecular systems. READ MORE

10. Conformational Entropy and Protein Flexibility in Drug Design Studied by NMR Spectroscopy
Abstract : Proteins are complex molecules, present in all of the vital functions of life. The function of a protein is regulated by interactions between protein and other molecules. Drug design in pharmaceutical science aims to regulate the function of a protein by the design of synthesized molecules that binds to a protein with high affinity. READ MORE
