Download or read book The Hydrogen Bond and the Water Molecule written by Yves Marechal and published by Elsevier. This book was released on 2006-12-11 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hydrogen Bond and the Water Molecule offers a synthesis of what is known and currently being researched on the topic of hydrogen bonds and water molecules. The most simple water molecular, H2O, is a fascinating but poorly understood molecule. Its unique ability to attract an exceptionally large number of hydrogen bonds induces the formation of a dense "hydrogen bond network" that has the potential to modify the properties of the surrounding molecules and their reactivities. The crucial role that water molecules play is described in this book. The author begins by providing an overview of the thermodynamical and structural properties of H-bonds before examining their much less known dynamical properties, which makes them appear as centres of reactivity. Methods used to observe these components are also reviewed. In the second part of the book the role played by the dense H-bond network developed by H2O molecules is examined. First in ice, where it has important atmospheric consequences, then in liquid water, and finally in macromolecules where it sheds some original light on the fundamental question "How is it that without water and hydrogen bonds life would not exist?". This book will be of interest to researchers in the fields of physics, chemistry, biochemistry and molecular biology. It can also serve as a teaching aid for students attending course in chemical physics, chemistry or molecular biology. Engineers involved the water industry would benefit from reading this book, as would scientists working in pharmaceutics, cosmetics and materials. * overview of what is known and being researched on the topic of hydrogen bonds and water molecules * reviews methods used to observe interactions between water molecules and hydrogen bonds * examines role of H-bond network developed by H2O molecules
Download or read book Investigations of the Structure and Hydrogen Bonding of Water Molecules at Liquid Surfaces by Vibrational Sum Frequency Spectroscopy written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure and hydrogen bonding of water molecules provides this unique solvent with properties essential to many physical, chemical and biological processes. The intermolecular hydrogen bonding between water molecules in the bulk medium is disrupted at the surface, imparting the surface with unique structural and thermodynamic properties. In this article we provide an overview of a range of experimental studies from this laboratory in which the structure, orientation and hydrogen bonding of interfacial water molecules at liquid interfaces are directly probed by resonant vibrational sum frequency spectroscopy. The studies provide insight into the difference in water structure and hydrogen bonding at an air/water interface relative to the interface between two bulk immiscible liquids, namely the CCl4/H2O interface. Also described are studies aimed at understanding how the presence of a charged alkyl surfactant alters the structure of water at these two interfaces. In both cases field induced alignment of water molecules in the double layer region is prevalent. This induced alignment has been examined under a variety of experimental conditions. A series of isotopic dilution studies conducted for the first time at liquid surfaces are also described. In these studies the intermolecular and intramolecular coupling of vibrational modes in the water molecules are diminished. The results of these and above mentioned studies provide valuable information for those interested in developing theoretical descriptions of water at surfaces and interfaces.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents the fantastic world of water in all its different forms, from liquid to ice and snow. This book is amply illustrated with a large number of beautiful pictures with. Water plays a unique role in chemistry. The special properties of water are due to hydrogen bonding between the H2O molecules. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment, and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together.The unique properties of water are of great importance in our daily life. The origin of these special properties is often not recognized. Even among chemists and physicists, the fundamental facts are not always known. In spite of very active research, there are still many questions to be answered about the structure of liquid water, for instance.The book differs from most books on water as it covers basic facts about structure and properties as well as the influence of these properties in our daily life. Why does ice float on water? Why is the maximum density of water at 4°C? The beauty of snow crystals is amply illustrated, and many of the pictures are unique.
Download or read book Snow Ice and Other Wonders of Water written by Ivar Olovsson and published by World Scientific. This book was released on 2016 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book illustrates the fascinating world of the different forms of water - from ice and snow to liquid water. The water molecule, H2O, is the second most common molecule in the Universe (behind hydrogen, H2) and ice is the most abundant solid material. Snow and ice appear in a countless large number of different shapes and with properties which can be quite different. Detailed knowledge of the properties of snow is of great importance for the Sami people involved in reindeer herding and several hundred names are used to characterize the different types. The properties of ice and liquid water are very special and unique in several respects. In contrast to most other substances, the density of ice is lower than that of liquid water, which has many very important consequences in our daily life. Water plays a unique role in chemistry and although tremendous research has been spent on this seemingly simple substance, there are still many unsolved questions about the structure of liquid water. The special properties of water are due to hydrogen bonding between the H2O molecules, and this book may be seen as a tribute to the hydrogen bond. The general properties of the hydrogen bond are treated in three separate papers. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together. -- Provided by publisher.

Download or read book Probing the Intermolecular Hydrogen Bonding of Water Molecules at the CCl Sub 4 Water Interface in the Presence of Charged Soluble Surfactant written by D. Gragson and published by . This book was released on 1998 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular structure and hydrogen bonding of water molecules at the CCl sub 4/water interface in the presence of a charged soluble surfactant has been explored in this study using vibrational sum frequency generation. By examining OH stretching modes that are highly sensitive to the local hydrogen bonding environment it is found that water molecules at the CCl sub 4/water interface both in the presence and absence of a charged soluble surfactant are predominantly in a tetrahedral arrangement much like the structure of ice. Isotopic dilution studies have been employed to further characterize this ice-like interfacial structure. A blue-shift of approximately 120 cm-1 of the ice-like OH stretching mode is observed upon dilution with D2O. The first vibrational spectra of the OH stretching mode from uncoupled HOD molecules at the CCl sub 4/water interface is also reported.
Download or read book Advanced Mineralogy written by A. S. Marfunin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: All existing introductory reviews of mineralogy are written accord ing to the same algorithm, sometimes called the "Dana System of Mineralogy". Even modern advanced handbooks, which are cer tainly necessary, include basic data on minerals and are essentially descriptive. When basic information on the chemistry, structure, optical and physical properties, distinguished features and para genesis of 200-400 minerals is presented, then there is practically no further space available to include new ideas and concepts based on recent mineral studies. A possible solution to this dilemma would be to present a book beginning where introductory textbooks end for those already famil iar with the elementary concepts. Such a volume would be tailored to specialists in all fields of science and industry, interested in the most recent results in mineralogy. This approach may be called Advanced Mineralogy. Here, an attempt has been made to survey the current possibilities and aims in mineral matter investigations, including the main characteristics of all the methods, the most important problems and topics of mineral ogy, and related studies. The individual volumes are composed of short, condensed chap ters. Each chapter presents in a complete, albeit condensed, form specific problems, methods, theories, and directions of investigations, and estimates their importance and strategic position in science and industry.

Download or read book Probing the Structure of Water Molecules at an Oil Water Interface in the Presence of a Charged Soluble Surfactant Through Isotopic Dilution Studies written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have employed vibrational sum frequency generation (VSFG) to obtain the first vibrational spectra of water molecules at an oil/water interface in the presence of a charged, soluble surfactant. By examining OH stretching modes that are highly sensitive to the local hydrogen bonding environment, we have been able to compare the structure of interfacial water molecules with the structure of bulk water molecules determined from previous studies. From the VSFG spectra we infer that there is more extensive hydrogen bonding between neighboring water molecules at the CCl4/water interface as compared to water molecules in the bulk aqueous phase. The presence of a charged surfactant enhances the SF response in the OH stretching spectral region in a manner similar to what we have previously observed at the air/water interface. To further probe the hydrogen bonding of water molecules at the oil/water interface we have employed VSFG to study mixed samples of H2O and D2O.
