Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognized that metal spin states play a central role in the reactivity of important biomolecules, in industrial catalysis and in spin crossover compounds. As the fields of inorganic chemistry and catalysis move towards the use of cheap, non-toxic first row transition metals, it is essential to understand the important role of spin states in influencing molecular structure, bonding and reactivity. Spin States in Biochemistry and Inorganic Chemistry provides a complete picture on the importance of spin states for reactivity in biochemistry and inorganic chemistry, presenting both theoretical and experimental perspectives. The successes and pitfalls of theoretical methods such as DFT, ligand-field theory and coupled cluster theory are discussed, and these methods are applied in studies throughout the book. Important spectroscopic techniques to determine spin states in transition metal complexes and proteins are explained, and the use of NMR for the analysis of spin densities is described. Topics covered include: DFT and ab initio wavefunction approaches to spin states Experimental techniques for determining spin states Molecular discovery in spin crossover Multiple spin state scenarios in organometallic reactivity and gas phase reactions Transition-metal complexes involving redox non-innocent ligands Polynuclear iron sulfur clusters Molecular magnetism NMR analysis of spin densities This book is a valuable reference for researchers working in bioinorganic and inorganic chemistry, computational chemistry, organometallic chemistry, catalysis, spin-crossover materials, materials science, biophysics and pharmaceutical chemistry.

Download or read book Ligand Field Theory and Its Applications written by Brian N. Figgis and published by Wiley-VCH. This book was released on 2000 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete, up-to-date treatment of ligand field theory and its applications Ligand Field Theory and Its Applications presents an up-to-date account of ligand field theory, the model currently used to describe the metal-ligand interactions in transition metal compounds, and the way it is used to interpret the physical properties of the complexes. It examines the traditional electrostatic crystal field model, still widely used by physicists, as well as covalent approaches such as the angular overlap model, which interprets the metal ligand interactions using parameters relating directly to chemical behavior. Written by internationally recognized experts in the field, this book provides a comparison between ligand field theory and more sophisticated treatments as well as an account of the methods used to calculate the energy levels in compounds of the transition metals. It also covers physical properties such as stereochemistry, light absorption, and magnetic behavior. An emphasis on the interpretation of experimental results broadens the book's field of interest beyond transition metal chemistry into the many other areas where these metal ions play an important role. As clear and accessible as Brian Figgis's 1966 classic Introduction to Ligand Fields, this new book provides inorganic and bioinorganic chemists as well as physical chemists, chemical physicists, and spectroscopists with a much-needed overview of the many significant changes that have taken place in ligand field theory over the past 30 years.
Download or read book Synthesis and Technique in Inorganic Chemistry written by Gregory S. Girolami and published by University Science Books. This book was released on 1999 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previously by Angelici, this laboratory manual for an upper-level undergraduate or graduate course in inorganic synthesis has for many years been the standard in the field. In this newly revised third edition, the manual has been extensively updated to reflect new developments in inorganic chemistry. Twenty-three experiments are divided into five sections: solid state chemistry, main group chemistry, coordination chemistry, organometallic chemistry, and bioinorganic chemistry. The included experiments are safe, have been thoroughly tested to ensure reproducibility, are illustrative of modern issues in inorganic chemistry, and are capable of being performed in one or two laboratory periods of three or four hours. Because facilities vary from school to school, the authors have included a broad range of experiments to help provide a meaningful course in almost any academic setting. Each clearly written & illustrated experiment begins with an introduction that hig! hlights the theme of the experiment, often including a discussion of a particular characterization method that will be used, followed by the experimental procedure, a set of problems, a listing of suggested Independent Studies, and literature references.

Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Supramolecular Chemistry will relate recent developments and new exciting approaches in supramolecular chemistry. In supramolecular chemistry, our aim is to understand molecular chemistry beyond the covalent bond - the series will concentrate on goal-orientated supramolecular chemistry. Perspectives in Supramolecular Chemistry will reflect research which develops supramolecular structures with specific new properties, such as recognition, transport and simulation of biosystems or new materials. The series will cover all areas from theoretical and modelling aspects through organic and inorganic chemistry and biochemistry to materials, solid-state and polymer sciences reflecting the many and varied applications of supramolecular structures in modern chemistry. Transition Metals in Supramolecular Chemistry Edited by Jean-Pierre Sauvage, Université Louis Pasteur, Strasbourg, France The chemistry of weak forces and non-covalent interactions as pioneered by Pedersen, Lehn and Cram is considered to be the origin of modern supramolecular chemistry. 30 years ago transition metals and their complexes were not regarded as important to this science. Transition Metals in Supramolecular Chemistry clearly demonstrates that today, transition metal complexes are routinely used to build large multicomponent architectures which display new and exciting applications including molecular switches, liquid crystals, and molecular magnets. Contents * Ligand and Metal Control of Self-Assembly in Supramolecular Chemistry * Bistability in Iron (II) Spin-Crossover Systems: A Supramolecular Function * Luminescent Sensors with and for Transition Metals * The Chirality of Polynuclear Transition Metal Complexes * Design and Serendipity in the Synthesis of Polynuclear Compounds of the 3d-metals * Rotaxanes: From Random to Transition Metal-Templated Threading of Rings at the Molecular Level * Metallomesogens - Supramolecular Organisation of Metal Complexes in Fluid Phases * Self-Assembly of Interlocked Structures with Cucurbituril Metal Ions and Metal Complexes Reflecting contemporary science, Transition Metals in Supramolecular Chemistry will inspire scientists and students interested in coordination chemistry, magnetochemistry, molecular sensors and switches, liquid crystals and artificial systems.
