1. 1. Chloromethane Complexation by Cryptophanes : Host-Guest Chemistry Investigated by NMR and Quantum Chemical Calculations

   Författare :Zoltan Takacs; Jozef Kowalewski; Mikael Akke; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Host–guest complexes; inclusion phenomenon; cryptophanes; NMR; kinetics; activation energy; dipolar interaction; exchange; quantum chemical optimization; calculated chemical shifts; NOESY; cavity size; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : Host–guest complexes are widely investigated because of their importance in many industrial applications. The investigation of their physico–chemical properties helps understanding the inclusion phenomenon. The hosts investigated in this work are cryptophane molecules possessing a hydrophobic cavity.

3. 2. Free Molecular and Metal Clusters Studied by Synchrotron Radiation Based Electron Spectroscopy

   Författare :Aldana Rosso; Svante Svensson; Olle Björneholm; Maxim Tchaplyguine; Gunnar Öhrwall; Uwe Hergenhahn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; free clusters; molecular clusters; metal clusters; photoelectron spectroscopy; synchrotron radiation; local structure; core level spectroscopy; auger spectroscopy; heterogeneous clusters; nucleation; bromomethane; chloromethane; benzene; bromobenzene; chlorobenzene; potassium; sodium; simple metals; Physics; Fysik;

   Sammanfattning : The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. LÄS MER
