Note Editore

The first volume devoted entirely to Electron Spin Echo Envelope Modulation (ESEEM) Spectroscopy

This valuable book provides an introduction and broad survey of topics in ESEEM spectroscopy, including the theory, instrumentation, peculiarities of ESE experiments, and analysis of experimental data with particular emphasis on orientationally disordered systems. Applications of ESEEM spectroscopy to study chemically and biologically important paramagnetic centers in single crystals, amorphous solids, and powders are discussed as well. Electron Spin Echo Envelope Modulation (ESEEM) Spectroscopy will benefit specialists in magnetic resonance spectroscopy, physicists, chemists, and biologists who use magnetic resonance in their research.
