    <dcterms:abstract xml:lang="eng">Distance determination with pulsed EPR has become an important technique for the structural investigation of biomacromolecules, with double electron–electron resonance spectroscopy (DEER) as the most important method. Gd&lt;sup&gt;III&lt;/sup&gt;-based spin labels are one of the most frequently used spin labels for DEER owing to their stability against reduction, high magnetic moment, and absence of orientation selection. A disadvantage of Gd&lt;sup&gt;III&lt;/sup&gt;–Gd&lt;sup&gt;III&lt;/sup&gt; DEER is the low modulation depth due to the broad EPR spectrum of Gd&lt;sup&gt;III&lt;/sup&gt;. Here, we introduce laser-induced magnetic dipole spectroscopy (LaserIMD) with a spin pair consisting of Gd&lt;sup&gt;III&lt;/sup&gt;(PymiMTA) and a photoexcited porphyrin as an alternative technique. We show that the excited state of the porphyrin is not disturbed by the presence of the Gd&lt;sup&gt;III&lt;/sup&gt; complex and that herewith modulation depths of almost 40% are possible. This is significantly higher than the value of 7.2% that was achieved with Gd&lt;sup&gt;III&lt;/sup&gt;–Gd&lt;sup&gt;III&lt;/sup&gt; DEER.</dcterms:abstract>
