Spin labelling with trityls: To gather information about the structure and dynamics of trityl radicals, spin-labelled polymers were measured with pulsed electron–electron double resonance (PELDOR) and double-quantum coherence (DQC). This study demonstrates that trityl radicals have great potential as spin labels that eliminate some limitations of nitroxide spin labels.
