In the last few years, much attention has been given by theoretical chemists to the development of more accurate model functionals and faster computational techniques including excited electronic states. The 8th International Conference on the Applications of Density Functional Theory to Chemistry and Physics, held in Rome, Italy, on 6-10 September 1999, gathered chemists and physicists to present and discuss state-of-the-art methodological developments and applications of density functional theory (DFT) to increasingly complex systems. The scientists shared their knowledge and experience in...

The subject of this book is EPR Spectroscopy of systems in which two or more spins are magnetically coupled. These systems are relevant to many different scientific areas, ranging from chemistry to solid state physics and to biology. The book is based on the spin hamiltonian approach and extensive use is made of irreducible tensor techniques. The most novel feature is that for the first time the whole field is brought together including pairs, oligonuclear species and infinite species, in an attempt to provide a unitary approach. The book collects in one place information which up to now has...

From chemistry to solid state physics to biology, the applications of Electron Paramagnetic Resonance (EPR) are relevant to many areas. This unified treatment is based on the spin Hamiltonian approach and makes extensive use of irreducible tensor techniques to analyze systems in which two or more spins are magnetically coupled. This edition contains a new Introduction by coauthor Dante Gatteschi, a pioneer and scholar of molecular magnetism.
The first two chapters review the foundations of exchange interactions, followed by examinations of the spectra of pairs and clusters, relaxation in...
