Abstract excerpt

Electron Paramagnetic Resonance (EPR) spectroscopy is a powerful method for unraveling structures and dynamics of biomolecules. Out of the EPR tool box, Pulsed Electron-Electron Double Resonance spectroscopy (PELDOR or DEER) enables one to resolve such structures by providing distances between spin centers on the nanometer scale. Most commonly, both spin centers are spin labels or one is a spin label and the...
