Electron Paramagnetic Resonance (EPR) Volume 18 highlights major developments in this area reported in 2001 and 2002, with results being set into the context of earlier work and presented as a set of critical yet coherent overviews. The topics covered describe contrasting types of application ranging from biological areas such as EPR studies of free-radical reactions in biology and medically-related systems to experimental developments and applications involving EPR imaging the use of very high fields and time-resolved methods. Critical and up-to-the-minute reviews of advances involving the design of spin-traps advances in spin-labelling paramagnetic centres on solid surfaces exchange-coupled oligomers metalloproteins and radicals in flavoenzymes are also included. As EPR continues to find new applications in virtually all areas of modern science including physics chemistry biology and materials science this series caters not only for experts in the field but also those wishing to gain a general overview of EPR applications in a given area.
