A pulsed electron paramagnetic resonance spectrometer comprises: a microwave excitation generating unit for generating at least one microwave pulse; a microwave conducting unit comprising a resonant cavity and a microwave transmission line for transmitting microwaves, wherein the microwave transmission line ...
Pulse electron paramagnetic resonance (pulse EPR) is a spectroscopic technique that entails observing the time evolution of the magnetization of a paramagnetic species in the presence of a static magnetic field when it is excited by one or several resonant microwave pulses. This kind of excitation i...

Pulsed dipolar electron paramagnetic resonance spectroscopy (PDS) is a valuable method for determining biomolecular structures and their conformational changes during function. Often, this method is applied to paramagnetic metal ions that are either intrinsic co‐factors of biomolecules or introduced into ...
To have a closer look at the protein structure, pulsed electron paramagnetic resonance (EPR) spectroscopy has been used after site-specifically spin-labeling the LHCII apoprotein [23], [24], [25]. In these experiments, the protein folding and complex assembly process was stopped by rapid manual...
