TL;DR: A four-pulse version of the pulse double electron-electron resonance (DEER) experiment is presented, which is designed for the determination of interradical distances on a nanoscopic length-scale and shows improved signal-to-noise ratio.

TL;DR: A four-pulse version of the pulsed double electron electron resonance (DEER) experiment has been applied to a series of TEMPO diradicals with well-defined interradical distances ranging from 1.4 to 2.8 nm, allowing broad distributions of electron-electron distances to be measured without dead-time artifacts.

TL;DR: Two single-frequency techniques for refocusing (SIFTER) dipolar couplings between electron spins are introduced in this article, based on the solid-echo and Jeener-Broekaert sequences, and open up new routes to high-resolution two-dimensional EPR spectroscopy with only moderate requirements on the spectrometer.

TL;DR: The synthesis of rod- and star-shaped compounds carrying two or three spin labels as end groups is described, which were obtained through Pd-Cu-catalyzed alkynyl-aryl coupling and alkyne dimerization in the presence of oxygen using p-phenyleneethynylene as the basic shape-persistent building block.

TL;DR: In this article, double electron-electron resonance (DEER) spectroscopy is introduced as a new tool for the characterization of mesoscopic structures in polymers, which can be applied to the measurement of ion cluster sizes and intercluster distances in ionically endcapped polymers by using ionic spin probes that attach themselves to the surface of the ion clusters.
