  2. 1. Stereoelectronic effects in nucleosides and nucleotides

    Author : Christophe Thibaudeau; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi; bioorganisk kemi; Biorganic Chemistry;

    Abstract : This thesis is based on 12 original publications from 1994-98. Intramolecular stereoelectronicforces (anomeric and gauche effects), beside intermolecular forces such as hydrogen bonding,base stacking, electrostatics and hydration, have been found to be responsible for the localstructural changes of DNA and RNA and their components.

  5. 3. Studies on the Non-covalent Interactions (Stereoelectronics, Stacking and Hydrogen Bonding) in the Self-assembly of DNA and RNA

    Author : Parag Acharya; Jyoti Chattopadhyaya; Frank Seela; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; nucleic acids; NMR; Stereoelectronic effects; Hydrogen Bonding; Stacking; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Abstract : This thesis is based on ten publications (Papers I-X). The phosphodiester backbone makes DNA or RNA to behave as polyelectrolyte, the pentose sugar gives the flexibility, and the aglycones promote the self-assembly or the ligand-binding process. READ MORE

  6. 4. Theoretical Study of the Electronic Factor in Electron Transfer Reactions

    Author : Manuel Braga; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The electronic factor D is calculated for a number of organic and biological electron transfer systems. Quantum chemical methods at different levels of accuracy are used: ab initio Hartree-Fock, broken-symmetry, and correlation-corrected methods such as multiconfigurational second-order perturbation theory, and also the semiempirical CNDO/S method for very large systems.
