Book Description
Most organic molecules retain their integrity when dissolved, and even though in such cases the effects exerted by solvents are, in the language of the coordination chemist, of the "outer sphere" kind, the choice of solvent can be critical to the successful outcome of an operation or preparation. Solubilities of reactants and products must be taken into account, and even if the organic principals in the reactions retain their integrity, many of the reagents are electrolytes, and their state of aggregation will affect their reactivity. In testifying to the importance of understanding solute-solvent interactions I draw attention to a large class of inorganic species for which the involvement in the chemical and physical properties by the solvent is even more deeply seated. It is comprised by the large body of metal atoms in low oxidation states for which solvent molecules intervene as reagents. At the same time, because the ions carry charges, the effects arising from outer sphere interactions are usually greater than they are for neutral molecules. To cite an example: when FeCb(s) is dissolved in water to form a dilute - say O. OlO- solution there is a complete reorganization of the coordination sphere of the cation. Whereas in the solid each cation is surrounded by six chloride ions, in the solution the dominant form is [Fe(H20)6]3+ followed by [Fe(H20)sCI]2+, [Fe(H20)4CI2]+, etc. in rapidly decreasing abundance.

Book Description
This 4th edition of Handbook of Solvents, Volume 1, contains the most recent findings and trends in solvent applications. It is a comprehensive survey of the science of solvents and their properties, covering all aspects of solvent behavior that are relevant to their use in chemical and related industries including agricultural and technical processes, inorganic synthesis and materials chemistry, and more. Divided into two volumes, this first volume covers high-level information on the physical chemical properties of the most relevant solvent systems. Each chapter is focused on a specific aspect of solvent properties that determine its selection, such as the effect on properties of solutes and solutions, properties of different groups of solvents, and the summary of their applications' effect on health and the environment (given in tabulated form). Also covered is swelling of solids in solvents, solvent diffusion and drying processes, nature of the interaction of solvent and solute in solutions, acid-base interactions, the effect of solvents on spectral and other electronic properties of solutions, the effect of solvents on the rheology of the solution, aggregation of solutes, permeability, molecular structure, crystallinity, configuration, conformation of dissolved high molecular weight compounds, and the effect of solvents on chemical reactions and reactivity of dissolved substances. With insight from specialists in a broad array of different areas and written with an interdisciplinary audience in mind, this thoroughly revised 4th edition provides readers with a complete overview of all the organic solvents available for industrial applications today. The book contains numerous references to key sources of more detailed information, and together with Handbook of Solvents Volume 2: Use, Health, and Environment; Databook of Green Solvents; and Databook of Solvents, represents the most comprehensive and up-to-date information ever published on solvents. - Provides key insights that will help engineers and scientists select the best solvent for the job - Includes practical information and ideas on how to improve existing processes involving solvents - Presents the latest advances in solvent technology and their applications

Book Description
This book sheds light on the molecular aspects of liquids and liquid-based materials such as organic or inorganic liquids, ionic liquids, proteins, biomaterials, and soft materials including gels. The reader discovers how the molecular basics of such systems are connected with their properties, dynamics, and functions. Once the use and application of liquids and liquid-based materials are understood, the book becomes a source of the latest, detailed knowledge of their structures, dynamics, and functions emerging from molecularity. The systems discussed in the book have structural dimensions varying from nanometers to millimeters, thus the precise estimation of structures and dynamics from experimental, theoretical, and simulation methods is of crucial importance. Outlines of the practical knowledge needed in research and development are helpfully included in the book.

Book Description
Why to apply solid-state NMR? - By now, we should have learned that NMR is mainly used for the study of molecules in solution, while x-ray diffraction is the method of choice for solids. Based on this fact, the two recent 'NMR-Nobelprizes' went indeed into the liquid phase: my own one eleven years ago, and particularly the most recent one to Kurt Wuthrich. His prize is beyond any doubts very well justified. His contribution towards the study of biomolecules in solution, in their native (or almost native) environment is truly monumental. We all will profit from it indirectly when one of our future diseases will be cured with better drugs, based on the insightful knowledge gained through liquid-state NMR. Two fields of NMR are still left out of the Nobel Prize game: magnetic reso nance imaging (MRI) and solid-state NMR. The disrespect for MRI in Stockholm is particularly difficult to understand; but this is not a subject to be discussed at the present place. Solid-state NMR is the third of the three great fields of NMR, powerful already today and very promising for the near future.
