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 (see figure).
