16. Photoelectron Spectroscopy on Atoms, Molecules and Clusters : The Geometric and Electronic Structure Studied by Synchrotron Radiation and Lasers
Sammanfattning : Atoms, molecules and clusters all constitute building blocks of macroscopic matter. Therefore, understanding the electronic and geometrical properties of such systems is the key to understanding the properties of solid state objects. LÄS MER
17. Infrared spectroscopy : Method development and ligand binding studies
Sammanfattning : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. LÄS MER
18. Conformations of Flexible Oligosaccharides : Molecular Simulations and NMR spectroscopy
Sammanfattning : The conformational preferences of several oligosaccharides are investigated herein using a combination of NMR spectroscopy and molecular dynamics (MD) simulations, focusing on the torsion angles associated with the glycosidic linkages.Strategies for obtaining usable J-HMBC spectra for carbons with an adjacent 13C label are described.

19. Precision molecular spectroscopy in the near- and mid-infrared using frequency comb-based Fourier transform spectrometers
Sammanfattning : Absorption spectroscopy is a powerful scientific tool for non-invasive and remote sensing applications ranging from atmospheric monitoring to astrophysics. In spectroscopic detection schemes it is necessary to have spectral models for any molecular species to be detected or quantified. LÄS MER
20. Molecular orientation in cellulose fibers and composites
Sammanfattning : The scope of this thesis is to quantitatively investigate the molecular orientation distribution of regenerated cellulose fibers and composites. The molecular orientation is known to affect macroscopic properties such as tensile strength of the fiber. LÄS MER
