Transition ion electron paramagnetic resonance is an important tool for the identification and characterisation of transition and metal ions. In this book the author presents a new perspective which unifies the main features of field-swept EPR of anisotropic systems, and account for the origin of asymetric lineshapes, linewidth anisotropy and strain broadening. A large number of spectra are shown, as familiarity with the shape of typical spectra is essential to good practice in EPR. The book also includes a wide range of examples including transition ions in crystals, glasses, semiconductors, phase transitions, proteins and other biological systems. This text provides an introduction to transition ion EPR at a level appropriate to beginning graduate students in physics or chemistry. It is also suitable for graduate students from other disciplines with a resonable background in quantum mechanics and spectroscopy, and will be of interest to all those whose work involves the use of transition ion EPR techniques.
