  1. 1. An Infrared Study of Intermolecular Interactions in Gaseous Hydrogen Bonded Molecular Complexes

    Författare :René Wugt Larsen; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intermolecular potential energy surface; Physical chemistry; Fysikalisk kemi; synchrotron radiation; infrared absorption spectroscopy; intermolecular vibration; molecular complex; Intermolecular interactions; hydrogen bond;

    Sammanfattning : Intermolecular interactions are responsible for the deviations of gases from ideality, determine the three- dimensional structure and folding dynamics of biological molecules, and the binding of molecules to surfaces as in heterogeneous catalysis. The hydrogen bond is the most important intermolecular interaction. LÄS MER

  3. 2. Intermolecular interactions in liquids : a nuclear spin relaxation and computer simulation study

    Författare :Arnold Maliniak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : .... LÄS MER

  4. 3. Intra- and intermolecular interactions in proteins : Studies of marginally hydrophobic transmembrane alpha-helices and protein-protein interactions

    Författare :Linnea E Hedin; Arne Elofsson; Susana Cristobal; Ismael Mingarro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane proteins; membrane insertion; marginally hydrophobic helix; hydrophobicity; protein-protein interactions; LacY; GltPh; Cell and molecular biology; Cell- och molekylärbiologi; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : Most of the processes in a living cell are carried out by proteins. Depending on the needs of the cell, different proteins will interact and form the molecular machines demanded for the moment. LÄS MER

  5. 4. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Författare :Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    Sammanfattning : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. LÄS MER

  7. 5. Intermolecular interactions in hydrogen bonded 1:1 molecular complexes. A matrix isolation study

    Författare :Anders Engdahl; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; infrared laser irradiation; dimethyl ether; water dimer; hydrogen chloride; formamide; acetone; formic acid; ammonia; water; intermolecular; matrix isolation; FIR; FTIR; infrared; isomerisation; ab initio; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. LÄS MER
