title: Rapid-Scan EPR of Nitroxide Spin Labels and Semiquinones.
abstract: Rapid-scan electron paramagnetic resonance is based on continuous direct detection of the spin response as the magnetic field is scanned upfield and downfield through resonance thousands of times per second. The method provides improved signal-to-noise for a wide range of samples, including rapidly tumbling and immobilized radicals. This chapter provides an introduction to the method and practical examples of implementation for organic radicals.
