1. Trauma, Posttraumatic Stress and Dissociation Among Swedish Adolescents : Evaluation of Questionnaires
Sammanfattning : The main aim of this thesis has been to investigate trauma and dissociation among Swedish adolescents and to evaluate the psychometric properties such as reliability and various kinds of validity of three screening instruments for assessment of dissociation and other symptoms of post traumatic stress. The three instruments in question have been Dis-Q-Sweden, A-DES and TSCC, the symptoms measured by these instruments are neither easy to capture nor easy for the adolescent to talk about. LÄS MER
2. Microscopic Modeling of Exciton Propagation and Dissociation in Two-Dimensional Materials
Sammanfattning : Atomically thin materials have been in the spotlight of research during the last decade due to their exceptional properties, providing a platform for the study of novel physical phenomena. In particular, transition metal dichalcogenides (TMDs) have emerged as promising atomically thin materials for future optoelectronic applications owing to their strong light-matter interaction and their high tunability.

3. Dissociation dynamics of highly excited molecules: Theory and Experiment
Sammanfattning : This thesis presents studies on dissociation of two model molecules: Butadiene and Cyclopropane. Tunable synchrotron radiation was used to ionize or excite the molecules in the gas phase, and the momentum correlation of the resulting fragment ions were measured using a 3D momenta coincident ion spectroscopy.

4. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics
Sammanfattning : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.

5. High Rate Electron Capture Dissociation Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
Sammanfattning : Advances in science and technology during the past decade have greatly enhanced the level of the structural investigation of macromolecules – peptides and proteins. Biological mass spectrometry has become one of the most precise and sensitive techniques in peptide and protein analysis. LÄS MER
