In this protocol, we describe the facile synthesis of the nitroxide spin-label 2,2,5,5-tetramethyl-pyrrolin-1-oxyl-3-acetylene (TPA) and then its coupling to DNA/RNA through Sonogashira cross-coupling during automated solid-phase synthesis. Subsequently, we explain how to perform distance measurements between two such spin-labels on
