  2. 1. Dissociation dynamics of highly excited molecules: Theory and Experiment

    Author : Shabnam Oghbaie; Synkrotronljusfysik; []
    Keywords : Molecular dissociation; core-electron excitation; double ionization; femtoseconds molecular dynamics; Isomerization; symmetry breaking; momentum imaging; site-selective dissociation; butadiene; cyclopropane; nuclear dynamics; Auger decay;

    Abstract : 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. 2. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics

    Author : Florian Burmeister; Eckart Rühl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Photoelectron spectroscopy; HCl; DCl; Dissociation dynamics; Born-Oppenheimer approximation; Synchrotron radiation; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : 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. 3. Model Studies of Electron Transfer and Reaction Dynamics at Surfaces

    Author : Johan Strömquist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissociation; desorption; oxidation; hot precursors; surface chemical reaction; chemiluminescence; surface harpooning; charge transfer; electron emission; transient mobility; non-adiabaticity;

    Abstract : Charge-transfer is of key importance in many physical, chemical and biological processes, including surface reactions. This thesis consists of several theories for and model studies of surface reactions that are initiated by electron transfer between the surface to a molecule. READ MORE

  6. 4. Derivatisation of peptides for collision-induced dissociation mass spectrometry

    Author : Ingemar Lindh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This study is concerned with the mass spectrometric analysis of peptides C-terminally derivatised with aminosulphonic acids. The aim was to increase the sensitivity of detection and to simplify the fragmentation patterns obtained upon collision-induced dissociation. READ MORE

  7. 5. Electropermutation assisted by ion-exchange textile : removal of nitrate from drinking water

    Author : Carl-Ola Danielsson; Anders Dahlkild; Mårten Behm; Anna Velin; Gerald Pourcelly; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion-exchange textile; Ion-exchange membrane; Electropermutation; Electroextraction; Electrodialysis; Electrodeionisation; Modeling; Conducting spacer; Nitrate removal; Water treatment; Water dissociation; Fluid mechanics; Strömningsmekanik;

    Abstract : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. READ MORE
