Experimental Foundations Of Structural Chemistry

This book focuses on two main topics in fundamental structural chemistry: the properties of chemical bonding derived from the behavior of the microscopic particles and their wave functions, and the three-dimensional molecular and crystal structures. The principle that ?structure determines properties and properties reflect structures? is clearly demonstrated. This book emphasizes practical examples linking structure with properties and applications which provide invaluable insight for students, thus stimulating their mind to deal with problems in the topics concerned.

A concise description of models and quantitative parameters in structural chemistry and their interrelations, with 280 tables and >3000 references giving the most up-to-date experimental data on energy characteristics of atoms, molecules and crystals (ionisation potentials, electron affinities, bond energies, heats of phase transitions, band and lattice energies), optical properties (refractive index, polarisability), spectroscopic characteristics and geometrical parameters (bond distances and angles, coordination numbers) of substances in gaseous, liquid and solid states, in glasses and melts, for various thermodynamic conditions. Systems of metallic, covalent, ionic and van der Waals radii, effective atomic charges and other empirical and semi-empirical models are critically revised. Special attention is given to new and growing areas: structural studies of solids under high pressures and van der Waals molecules in gases. The book is addressed to researchers, academics, postgraduates and advanced-course students in crystallography, materials science, physical chemistry of solids.

This book explains key concepts in theoretical chemistry and explores practical applications in structural chemistry. For experimentalists, it highlights concepts that explain the underlying mechanisms of observed phenomena, and at the same time provides theoreticians with explanations of the principles and techniques that are important in property design. Themes covered include conceptual and applied wave functions and density functional theory (DFT) methods, electronegativity and hard and soft (Lewis) acid and base (HSAB) concepts, hybridization and aromaticity, molecular magnetism, spin transition and thermochromism. Offering insights into designing new properties in advanced functional materials, it is a valuable resource for undergraduates of physical chemistry, cluster chemistry and structure/reactivity courses as well as graduates and researchers in the fields of physical chemistry, chemical modeling and functional materials.

Experimental Quantum Chemistry is a comprehensive account of experimental quantum chemistry and covers topics ranging from basic quantum theory to atoms and ions, photons, electrons, and positrons. Nuclei, molecules, and free radicals are also discussed. This volume is comprised of eight chapters and begins with an overview of the basic experiments and ideas leading to the development of quantum theory, with special emphasis on the problems of chemistry. The main properties of electromagnetic radiation are then considered, along with the most important relations of electrons and positrons in chemistry; the quantum theory of isolated atoms and ions; the structure of nuclei and the main applications to organic chemistry; and the chemical structure and reactivity of molecules. The theoretical and experimental aspects of interpreting free radical structures on the basis of the molecular orbital and valence bond theories are also explored. The final chapter is devoted to the chemistry of the organic solid state, paying particular attention to the structure and molecular mobilities of organic solids, collective crystal states (excitons, phonons, and polaritons), energy transfer processes, and reactions in the solid state. This book should be of interest to physicists and organic chemists.

Determining the structure of molecules is a fundamental skill that all chemists must learn. Structural Methods in Molecular Inorganic Chemistry is designed to help readers interpret experimental data, understand the material published in modern journals of inorganic chemistry, and make decisions about what techniques will be the most useful in solving particular structural problems. Following a general introduction to the tools and concepts in structural chemistry, the following topics are covered in detail: • computational chemistry • nuclear magnetic resonance spectroscopy • electron paramagnetic resonance spectroscopy • Mössbauer spectroscopy • rotational spectra and rotational structure • vibrational spectroscopy • electronic characterization techniques • diffraction methods • mass spectrometry The final chapter presents a series of case histories, illustrating how chemists have applied a broad range of structural techniques to interpret and understand chemical systems. Throughout the textbook a strong connection is made between theoretical topics and the real world of practicing chemists. Each chapter concludes with problems and discussion questions, and a supporting website contains additional advanced material. Structural Methods in Molecular Inorganic Chemistry is an extensive update and sequel to the successful textbook Structural Methods in Inorganic Chemistry by Ebsworth, Rankin and Cradock. It is essential reading for all advanced students of chemistry, and a handy reference source for the professional chemist.

This volume is the fourth in the series and offers both quality and breadth. As a whole it reflects two increasingly discernible trends in modern structural chemistry. One trend is that parallel to the ever increasing specialization of techniques, there is a strong interaction between the techniques. This interaction crosses the boundaries between various experiments, between the experiments and computations, experiments and theory, and organic and inorganic chemistry. The other trend is the ever increasing penetration of the most modern aspects of structural chemistry the rest of chemistry, making the demarkation of structural chemistry increasingly fuzzy which is the most welcome development from a structural chemist's point of view.

This book presents active application aspects of theoretical chemistry, and is particularly intended for experimental chemists, ranging from graduate students to more professional researchers, who are developing new materials or searching for novel properties of the materials they work with. It not only addresses the fundamental aspects of theoretical chemistry but also provides abundant examples of applications based on the electronic structure analyses of actual systems. As the book demonstrates, these analyses can deepen our understanding of a variety of chemical phenomena, including the chemical reactivities and electronic properties of substances, in a bottom-up manner. By illustrating how electronic structure analyses can be effectively applied, the book introduces readers to the impressive potential of theoretical chemistry, which they can adapt for their own purposes, and without having to suffer through a parade of complex formulae.
