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.

Das trifft gleichermaßen für die Grundlagen- und angewandte Forschung wie für industrielle Anwendungen zu. Ausgehend von den Prinzipien der Katalyse und den katalytisch relevanten metallorganischen Elementarschritten werden wichtige metallkomplexkatalysierte Reaktionen behandelt, wobei das mechanistische Verständnis im Vordergrund steht. Besonderer Wert wird dabei auf aktuelle Entwicklungen gelegt. Asymmetrische Synthesen finden ausführlich Berücksichtigung und an ausgewählten Beispielen wird die katalytische Wirkung von Metalloenzymen aufgezeigt. Am Beispiel der Stickstofffixierung werden die drei großen Gebiete der Katalyse – die homogene, die heterogene und die enzymatische Katalyse – vergleichend betrachtet. In der 2. Auflage ist ein neues Kapitel zur Stickstofffixierung hinzugekommen. In diesem werden vergleichend die heterogen katalysierte Reaktion, die enzymatisch katalysierte Reaktion (Nitrogenasen) sowie die homogen katalysierte Reaktion gegenübergestellt.

Mössbauer spectroscopy is a profound analytical method which has nevertheless continued to develop. The authors now present a state-of-the art book which consists of two parts. The first part details the fundamentals of Mössbauer spectroscopy and is based on a book published in 1978 in the Springer series 'Inorganic Chemistry Concepts' by P. Gütlich, R. Link and A.X. Trautwein. The second part covers useful practical aspects of measurements, and the application of the techniques to many problems of materials characterization. The update includes the use of synchroton radiation and many instructive and illustrative examples in fields such as solid state chemistry, biology and physics, materials and the geosciences, as well as industrial applications. Special chapters on magnetic relaxation phenomena (S. Morup) and computation of hyperfine interaction parameters (F. Neese) are also included. The book concentrates on teaching the technique using theory as much as needed and as little as possible. The reader will learn the fundamentals of the technique and how to apply it to many problems of materials characterization. Transition metal chemistry, studied on the basis of the most widely used Mössbauer isotopes, will be in the foreground.
