    Effective core potentials and the structures of metallocenes (1995)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 53 (1995), S. 309-319 
    Details
    ISSN: 0020-7608
    Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical Physics

    Topics: Chemistry and Pharmacology
    Notes: The use of effective core potentials in the calculation of the geometrical parameters of the ferrocene molecule and its heavier analogs is reported. It is shown that a critical factor in these calculations is the efective core-core (ECC) potential and, in the absence of ECCs for first-row atoms that are involved in short bonds, calculations of the geometrical parameters are not reliable. Good agreement with experimental geometries may be obtained by using the Los Alamos ECPs for atoms of the second and higher rows of the periodic table at the MP2 level. DFT calculations have been performed and found to give numerical results comparable to MP2 in the same basis. © 1995 John Wiley & Sons, Inc.

    Virtual orbitals (1996)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 60 (1996), S. 793-801 
    Details
    ISSN: 0020-7608
    Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical Physics
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: It is shown that the conventional concepts based on the use of the HOMO and LUMO are founded on very questionable assumptions. In particular, it is shown both theoretically and computationally that the LUMO of almost all neutral atoms and molecules is a continuum function with energy zero. The LUMO of any SCF calculation is an artifact of the basis-expansion method. A proposal is made for the identification of the pair donor and pair acceptor orbitals which play the true role of the HOMO and LUMO. © 1996 John Wiley & Sons, Inc.

    Molecular fragments and the hybrid basis (1996)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 60 (1996), S. 173-183

    ISSN: 0020-7608

    Topics: Chemistry and Pharmacology
    Notes: A method of performing ab initio calculations of the electronic structure of fragments within a larger molecule is reported. The method uses the self-consistent group formalism of McWeeny together with the systematic use of a hybrid atomic orbital basis. The mutual compatibility of these two ideas is stressed and results are given for model calculations on fragments in saturated hydrocarbon chains and rings. © 1996 John Wiley & Sons, Inc.

    The organization of replication and transcription (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-06-12
    Description: Models for replication and transcription often display polymerases that track like locomotives along their DNA templates. However, recent evidence supports an alternative model in which DNA and RNA polymerases are immobilized by attachment to larger structures, where they reel in their templates and extrude newly made nucleic acids. These polymerases do not act independently; they are concentrated in discrete "factories," where they work together on many different templates. Evidence for models involving tracking and immobile polymerases is reviewed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cook, P R -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1999 Jun 11;284(5421):1790-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sir William Dunn School of Pathology, University of Oxford, South Parks Road, Oxford OX1 3RE, UK.
