The topics covered in this series describe contrasting types of Electron Paramagnetic Resonance (EPR) application, including EPR studies of free-radical reactions in biology and medically-related systems, experimental developments and applications involving EPR imaging, the use of very high fields, and time-resolved methods. EPR applications remain very significant in modern science and this volume compiles critical coverage of developments in the recent literature by a hand-picked group of researchers at the cutting-edge of the field.
