Download or read book Fundamental Studies of Carbon NH and Oxygen Rings and Other High Energy Density Molecular Systems written by Henry F. Schaefer and published by . This book was released on 1988 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of efficient and safe conventional (i.e., nonnuclear) propellants and/or fuels is a goal of obvious technological significance. A desirable quality of such a propellant is clearly a high ratio of energy release to mass. The present hypothesis rests on a simple, but previously unrecognized, analogy between oxygen and sulfur. Preliminary studies showed that the oxygen ring systems are sufficiently promising to warrant the detailed, high-level theoretical research reported here. Keywords: Quantum chemistry; Propellants; Oxygen compounds; Cyclic compounds. (kt).

Available in PDF, EPUB and Kindle. Book excerpt: The object of this research is to characterize the energetics, spectroscopic properties, and elementary chemical reactions (including unimolecular reactions) of the oxygen ring molecules O4 and O12 and related species. The approach used will exploit recent developments in ab initio molecular quantum mechanics. In a collaborative effort with ongoing experimentat research to identify and synthesize high energy density molecules, excited electronic states and positive ions of these species will be studied.

Download or read book The Nature of the Hydrogen Bond written by Gastone Gilli and published by OUP Oxford. This book was released on 2009-06-25 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen bond (H-bond) effects are known: it makes sea water liquid, joins cellulose microfibrils in trees, shapes DNA into genes and polypeptide chains into wool, hair, muscles or enzymes. Its true nature is less known and we may still wonder why O-H...O bond energies range from less than 1 to more than 30 kcal/mol without apparent reason. This H-bond puzzle is re-examined here from its very beginning and presented as an inclusive compilation of experimental H-bond energies and geometries. New concepts emerge from this analysis: new classes of systematically strong H-bonds (CAHBs and RAHBs: charge- and resonance-assisted H-bonds); full H-bond classification in six classes (the six chemical leitmotifs); and assessment of the covalent nature of strong H-bonds. This leads to three distinct but inter-consistent models able to rationalize the H-bond and predict its strength, based on classical VB theory, matching of donor-acceptor acid-base parameters (PA or pKa), or shape of the H-bond proton-transfer pathway. Applications survey a number of systems where strong H-bonds play an important functional role, namely drug-receptor binding, enzymatic catalysis, ion-transport through cell membranes, crystal design and molecular mechanisms of functional materials.

Download or read book The Weak Hydrogen Bond written by Gautam R. Desiraju and published by International Union of Crystal. This book was released on 2001 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weak or non-conventional hydrogen bond has been subject of intense scrutiny over recent years in several fields, in particular in structural chemistry, structural biology, and also in the pharmaceutical sciences. There is today a large body of experimental and theoretical evidenceconfirming that hydrogen bonds like C-H...O, N-H...pi, C-H...pi and even bonds like O-H...metal play distinctive roles in molecular recognition, guiding molecular association, and in determining molecular and supramolecular architectures. The relevant compound classes include organometalliccomplexes, organic and bio-organic systems, and also DNA and proteins. The book provides a comprehensive assessment of this interaction type, and is of interest to all those interested in structural and supramolecular science, including fields as crystal engineering and drug design.
