2. 1. Nuclear Dynamics in X-ray Absorption and Raman Scattering

   Author : Ivaylo Minkov; Faris Gelmukhanov; Knut Borve; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray scattering; theory; simulations; recoil; Doppler effect; nuclear dynamics; Auger; XPS; Theoretical chemistry; Teoretisk kemi;

   Abstract : This thesis presents theoretical studies of several x-ray spectroscopies - x-ray absorption, x-ray photoelectron emission, radiative and non-radiative resonant Raman scattering spectroscopy. The main focus point is investigating the influence of nuclear dynamics on these spectra for a variety of small molecules - naphthalene, biphenyl, ethylene, the water dimer, HCl, CO. READ MORE

   Abstract : Aqueous solutions were studied using photoelectron and Auger spectroscopy, based on synchrotron radiation and a liquid micro-jet setup. By varying the photon energy in photoelectron spectra, we depth profiled an aqueous tetrabutylammonium iodide (TBAI) solution. READ MORE

7. 5. Structure and Dynamics of Core-Excited Species

   Author : Oksana Travnikova; Maria Novella Piancastelli; Svante Svensson; Denis Ceolin; Pascal Lablanqui; Uppsala universitet; []
   Keywords : Physics; Synchrotron radiation; X-ray Photoelectron Spectroscopy XPS ; X-ray Absorption Spectroscopy XAS ; Resonant Auger Spectroscopy RAS ; Auger Electron Spectroscopy AES ; Energy-Selected Auger Electron PhotoIon COincidence ES-AEPICO ; core excitation; core ionization; linear free energy relationships LFER ; molecular-field splitting; substituent effects; nuclear dynamics; isomerization; Cl2; N2O; methane derivatives; allene; acetylacetone; Fysik;

   Abstract : In this thesis we have performed core-electron spectroscopy studies of gas phase molecular systems starting with smaller diatomic, continuing with triatomic and extending our research to more complex polyatomic ones. We can subdivide the results presented here into two categories: the first one focusing on electronic fine structure and effect of the chemical bonds on molecular core-levels and the other one dealing with nuclear dynamics induced by creation of a core hole.
