  • Structure and Dynamics of Solutions

    • Volumen 79
    • Hideyuki Ohtaki + 1 más
    • Inglés
    Recent advances in the study of structural and dynamic properties of solutions have provided a molecular picture of solute-solvent interactions. Although the study of thermodynamic as well as electronic properties of solutions have played a role in the development of research on the rate and mechanism of chemical reactions, such macroscopic and microscopic properties are insufficient for a deeper understanding of fast chemical and biological reactions. In order to fill the gap between the two extremes, it is necessary to know how molecules are arranged in solution and how they change their positions in both the short and long range. This book has been designed to meet these criteria.It is possible to develop a sound microscopic picture for reaction dynamics in solution without molecular-level knowledge of how reacting ionic or neutral species are solvated and how rapidly the molecular environment is changing with time. A variety of actual examples is given as to how and when modern molecular approaches can be used to solve specific solution problems. The following tools are discussed: x-ray and neutron diffraction, EXAFS, and XANES, molecular dynamics and Monte Carlo computer simulations, Raman, infrared, NMR, fluorescence, and photoelectron emission spectroscopic methods, conductance and viscosity measurements, high pressure techniques, and statistical mechanics methods. Static and dynamic properties of ionic solvation, molecular solvation, ion-pair formation, ligand exchange reactions, and typical organic solvents are useful for bridging the gap between classical thermodynamic studies and modern single-molecule studies in the gas phase.The book will be of interest to solution, physical, inorganic, analytical and structural chemists as well as to chemical kineticists.

    This book provides the most up-to-date and comprehensive coverage of the structures and properties of polysaccharides, methods for their characterization, de novo synthesis, and modification, as well as advances in structure/function correlations. Many of these topics are summarized for the first time.A brief survey of polysaccharide structures is given highlighting the most significant advances in analytical and spectroscopic technology (NMR, MS, etc.). A chapter is devoted to glycan properties, including conformational aspects, rheological and compatibility characteristics, etc. There is a comprehensive overview of the de novo synthesis of carbohydrate polymers, the transformation of glycans into novel types of polymers, and the preparation of linear and branched polysaccharide analogues and conjugates with synthetic polymers via chemical and enzymatic approaches. The book also details the factors controlling the uniformity of substitutions in homogeneous and heterogeneous derivatization processes and the elucidation of the substitution patterns of partially modified polysaccharides, through combined spectroscopic and statistical methods.One of the important developments in the glycan field is based on the increasing demand for greater control of the functional properties of these biopolymers. The book provides a very extensive account of various types of modifications, including selective and non-selective chemical techniques, biological methods that facilitate alterations or specific functional groups and properties through the application of synthetic or degradative enzymes, and mutational or recombinant DNA techniques. The coverage extends to the control of glycan integrity and molecular weight through chemical enzymatic, physical or other methods. Electrochemical modification techniques are also discussed.A particularly up-to-date and comprehensive review is given of polysaccharide structure/property relations. Here, the effects of primary structural parameters (composition, molecular size, branching, polyelectrolyte character and non-carbohydrate substituents) are discussed, as are factors which affect glycan solubility, viscosity and gel-forming capacity. Also included are the phenomena resulting from the interactions of polysaccharides with solvents, salts, polyols, surfactants, synthetic and biological polymers. The impact of glycan structural parameters on various biological activities, such as immunological, anticoagulant, and antitumour properties, is surveyed.The book features a foreword by Dr. R.H. Marchessault, and contains almost 2,000 references to the state-of-the-art in the field, as well as an extensive subject index, over 40 tables, and 130 schemes and illustrations.

  • The Physical Basis of Chemistry

    • 1 Edición
    • Warren S. Warren
    • Inglés
    If the descriptive text youre using for teaching general chemistry seems to lack sufficient mathematics and physics to make the results of its presentation of classical mechanics, molecular structure, and statisticsunderstand... youre not alone. Written to provide supplemental and mathematically challenging topics for the advanced lower-division undergraduate chemistry course, or the non-major, junior-level physical chemistry course, The Physical Basis of Chemistry will offer your students an opportunity to explore quantum mechanics, the Boltzmann distribution, and spectroscopy in a refreshingly compelling way.Posed and answered are questions concerning everyday phenomena: How can two discharging shotguns and two stereo speakers be used to contrast particles and waves? Why does a collision between one atom of gas and the wall of its container transfer momentum but not much energy? How does a microwave oven work? Why does carbon dioxide production heat the earth? Why are leaves green, water blue, and how do the eyes detect the difference? Unlike other texts on this subject, however, The Physical Basis of Chemistry deals directly with the substance of these questions, avoiding the use of predigested material more appropriate for memorization exercises than for actual concrete learning. The only prerequisite is first-semester calculus, or familiarity withderivatives of one variable.

    • Inglés
    Handbook of Hydrocarbons presents tables giving the most important physical properties of all hydrocarbons whose boiling points have been recorded, in such form that all compounds boiling at or near a given value are listed together and a specific hydrocarbon can be promptly located. These ends can be best accomplished by listing each hydrocarbon in each of two tables. The order in Table A is that of the boiling points at 760 mm Hg, and other properties are also given. In Table B, the compounds are in groups of the same empirical formula and same type and are arranged within groups alphabetically by parent compound. Table C lists alternate names, including common and trivial names, and Table D gives the numbering of representative cyclic hydrocarbons. The Handbook should offer real help to any investigator who wishes either to locate the properties of a specific hydrocarbon, or to obtain a quick summary of the indications which the literature affords as to what compounds may be present in a cut of known boiling point or range. Such investigators should include academic, institutional, government and industrial workers, not only in the predominantly hydrocarbon fields such as petroleum, natural gas, shale oil, coal, and rubber, but also in the chemical, ""petrochemical,"" and plastics fields.

    • Inglés
    The Conservation of Orbital Symmetry examines the principle of conservation of orbital symmetry and its use. The central content of the principle was that reactions occur readily when there is congruence between orbital symmetry characteristics of reactants and products, and only with difficulty when that congruence does not obtain—or to put it more succinctly, orbital symmetry is conserved in concerted reaction. This principle is expected to endure, whatever the language in which it may be couched, or whatever greater precision may be developed in its application and extension. The book opens with a review of the elementary aspects of the molecular orbital theory of bonding. This is followed by separate chapters on correlation diagrams, the conservation of orbital symmetry, theory of electrocyclic reactions, theory of cycloadditions and cycloreversions, and theory of sigmatropic reactions. Subsequent chapters deal with group transfers and eliminations; secondary conformational effects in concerted cycloaddition reactions; and generalized selection rules for pericyclic reactions.
