16. Theoretical calculations of heavy atom effects in magnetic resonance spectroscopy
Sammanfattning : This thesis presents quantum chemical calculations, applications of the response function formalism recently implemented within the framework of density functional theory (DFT) by our research group. The purpose of the calculations is to assess the performance of this perturbative approach to determining heavy atom effects on magnetic resonance parameters. LÄS MER
17. Molecular recognition and dynamics in proteins studied by NMR
Sammanfattning : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).

19. Electron-Phonon Interactions in Transition Metal Oxides Studied by Resonance Raman Scattering
Sammanfattning : In this thesis, studies of strong electron-phonon interactions in a number of transition metal oxides are presented. Two different electron-phonon interaction mechanisms are identified; Franck-Condon scattering and infrared active longitudinal optical (IR LO) two-phonon activation. LÄS MER
20. Density functional studies of EPR and NMR parameters of paramagnetic systems
Sammanfattning : Experimental methods based on the magnetic resonance phenomenon belong to the most widely used experimental techniques for investigations of molecular and electronic structure. The difficulty with such experiments, usually a proper interpretation of data obtained from high-resolution spectra, opens new challenges for pure theoretical methods. LÄS MER
