This comprehensive series of volumes on inorganic chemistry provides inorganic chemists with a forum for critical, authoritative evaluations of advances in every area of the discipline. Every volume reports recent progress with a significant, up-to-date selection of papers by internationally recognized researchers, complemented by detailed discussions and complete documentation. Each volume features a complete subject index and the series includes a cumulative index as well.
This volume was originally published in 1973. The nature of the non-symmetry determined aspects of ligand-field theory receives inadequate treatment in most texts. This book is concerned with the nature of the ligand-field parameters used to describe the electronic properties of transition metal complexes having cubic and lower symmetries. These radial parameters constitute the non-symmetry-determined part of ligand-field theory. Symmetry-based properties are discussed here only to emphasize the separate roles of splitting factors and symmetry. The reader is assumed to be familiar with the usual approach to ligand-field theory and with elementary group theory.
"The Theory of Atomic Spectra", surrrrnanzlllg all that was then known about the quantum theory of free atoms; and in 1961, J.S. Griffith published "The Theory of Transition Metal Ions", in which he combined the ideas in Condon and Shortley's book with those of Bethe, Schlapp, Penney and Van Vleck. All this work, however, was done by physicists, and the results were reported in a way which was more accessable to physicists than to chemists. In the meantime, Carl J. Ballhausen had been studying quantum theory with W. Moffitt at Harvard; and in 1962 (almost simultaneously with Griffith) he published his extremely important book, "Introduction to Ligand Field Theory". This influential book was ...
Innovation today . . . Practice tomorrow. PROGRESS in Inorganic Chemistry Today's cutting-edge chemical experimentation is a foretaste of thetechnical arsenal of tomorrow's chemist. Progress in InorganicChemistry affords instant and convenient access to every area ofinnovative chemical research and has long served as theprofessional chemist's index to the newest and influential turns ininorganic chemistry. Featuring the work of internationally renownedchemists, Volume 45 discusses: * Selective Recognition of Organic Molecules by Metallohosts (JamesW. Canary and Bruce C. Gibb, New York University) * Metallacrowns: A New Class of Molecular Recognition Agents(Vincent L. Pecoraro, Ann J. Stemmle...
In this book, a synthesis of old and new notions straddling the disciplines of physics and chemistry is described.
A discussion of recent developments in all aspects of computational chemistry.
Investigating the relationship between the magnetic properties and structure of molecules, molecular magnetochemistry, is an area of growing interest to scientists in a variety of fields, including physical, organic and inorganic chemistry, molecular physics, and biophysics. For the first time, systematic results on magnetic properties of molecules such as mean magnetic susceptibility, their anisotropies and principal magnetic axes are presented. Molecular Magnetochemistry is a comprehensive and up-to-date view on experimental methods not covered in previous volumes, including the Zeeman effect in vapor phase and magnetic birefringence of diamagnetic systems (Cotton-Mouton Effect). The relationship between magnetic and related electrical phenomena is also described, summing up experimental data on magnetic and electrical anisotropies and components of molecular quadrupole moments.
The Indaba 5 meeting, held in South Africa during August 2006, examined the progress being made to achieve first-principle understanding of molecular science and confirmed the need to better understand the mysteries and magic of molecules. This book explores the common ground to guide chemists, biologists, crystallographers, spectroscopists and theorists towards painting a holistic picture of scientific endeavor.
