This first introduction to the rapidly growing field of molecular magnetism is written with Masters and PhD students in mind, while postdocs and other newcomers will also find it an extremely useful guide. Adopting a clear didactic approach, the authors cover the fundamental concepts, providing many examples and give an overview of the most important techniques and key applications. Although the focus is one lanthanide ions, thus reflecting the current research in the field, the principles and the methods equally apply to other systems. The result is an excellent textbook from both a scientific and pedagogic point of view.

The unique properties and applications of transition metal compounds have long fascinated both physicists and chemists. This volume presents theoretical and experimental studies for a deeper understanding of the electronic and vibronic properties of these compounds. In particular, an introduction into properties of spin sublevels of dd*, dÂ*, and ÂÂ* states is given, and a modern ligand field theory based on the Angular Overlap Model is presented. In experimental case studies it is shown how to characterize different types of electronic transitions using modern methods of laser spectroscopy. Consequences of spin-orbit coupling, zero-field splittings, spin-lattice relaxations, chromophore-matrix interactions, Herzberg-Teller/Franck-Condon activities, and localization/delocalization properties are treated.

The chemistry of the transition metals is a vital part of undergraduate courses in inorganic chemistry and is an essential background for bioinorganic chemistry. This teaching text, together with the accompanying Periodic Table DVD-ROM, provides an introduction to the transition metals, examining the behaviour of the metals and their aqueous ions and complexes. The book begins, largely using interactive activities and video on the DVD, by introducing the reader to the chemistry of the first-row transition elements in different oxidation states, in particular +2 and +3, and their relative stability. This is followed by a study of coordination chemistry. Later chapters look at theories of metal-ligand bonding and the way models can be used to rationalise many of the properties of transition metals and their compounds, such as colour, magnetism and stereochemistry. Starting with the simple, yet powerful crystal-field approach, the book finishes with a largely pictorial treatment of molecular orbital theory. (A basic knowledge of atomic and molecular orbitals as applied to the main-Group elements is assumed.) The material in this book is designed to be used either as part of an undergraduate chemistry programme, or for self-directed study. Learning is facilitated through various key features, including: "interactive activities on the accompanying Periodic Table DVD "in-text questions with answers "full-colour diagrams "revision exercises on an associated website (www.rsc.org/metalsandlife) This book was written as part of the teaching material for the Open University course, S347 Metals and Life. An associated book, Metals and Life also published by RSC Publishing, explores the vital role that metals play in the physiology of animals and plants, and increasingly in medicine.

The study ofmagneticproperties as a method to determine molecularand electronic structure of the ground state has a long tradition, in particular as far as metal complexes and solids of the transition metals are concerned. In the early days of the development, the emphasiswas placedon the observation ofdeviationsfrom the "spin-only" magnetic moment, the underlying assumption being that the value of themomentatroomtemperaturewouldsufficetodetermine boththeoxidationstate of the metal and the stereochemistry of the complex. The increasing number of deviations from these simple rules shifted the interest of researchers to the more detailed study ofthe temperature dependence of the magnetic moment. Most of the experimentalresults was then limited to measurementson powderedsubstancesand totemperatures between 77 and 300 K. Although themajorityofdataarestillofthis type, magnetic studies down to or even below 4. 2 K have become more common within the last few years as the sophistication of the equipment has increased. In addition, the investigation of magnetic anisotropies and principal magnetic suscep­ tibilities received a new impetus. In order to make the best possible use of the theory, magnetism diagrams based on calculations by the ligand field theory were produced. As a rule, these diagrams show the effective magnetic moment as a function of the temperature and of any N additional parameters of interest. The first magnetism diagrams applicable to d electronicconfigurationswerepublished 30 yearsago byKotani. Thesediagrams are limited to the configurations (t2g)N, N = 1 to 4, in octahedral symmetry.

Recent developments in electronic structure theory have led to a new understanding of magnetic materials at the microscopic level. This enables a truly first-principles approach to investigations of technologically important magnetic materials. Among the advances treated here have been practical schemes for handling non-collinear magnetic systems, including relativity, and an understanding of the origins and role of orbital magnetism within band structure formalisms. This book provides deep theoretical insight into magnetism, mahneatic materials, and magnetic systems. It covers these recent developments with review articles by some of the main originators of these developments.

Introduction to Magnetochemistry provides an introduction to the more important aspects of magnetochemistry. The measurement of magnetic moment has been one of the most consistently useful to coordination chemists. For teaching purposes it provides a simple method of illustrating the ideas of electronic structure, and in research it can provide fundamental information about the bonding and stereochemistry of complexes. The book contains six chapters covering topics such as free atoms and ions, transition metal complexes, crystal field theory, second and third row transition metal complexes, antiferromagnetism, and spin-pairing of electrons. The final chapter describes important experimental methods and then to shows briefly the way in which the problems of interpretation may be tackled.
