Spin Resonance Spectroscopy

Spin Resonance Spectroscopy: Principles and Applications presents the principles, recent advancements and applications of nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) in a single multi-disciplinary reference. Spin resonance spectroscopic techniques through NMR and EPR are widely used by chemists, physicists, biologists and medicinal chemists. This book addresses the need for new spin resonance spectroscopy content while also presenting the principles, recent advancements and applications of NMR and EPR simultaneously. Ideal for researchers and students alike, the book provides a single source of NMR and EPR applications using a dynamic, holistic and multi-disciplinary approach.

• Presents a highly interdisciplinary approach by including NMR and EPR applications in chemistry, physics, biology and biotechnology
• Addresses both NMR and EPR, making its concepts and applications implementable in multiple resonance environments and core scientific disciplines
• Features a broad range of methods, examples and illustrations for both NMR and EPR to aid in retention and underscore key concepts
