Abstract
Long range distance measurement on RNA allow the determination of RNA folds. Here we report the site specific incorporation of nitroxide spin labels at U,C and A by "on column synthesis". PELDOR (Pulsed Electron Double Resonance) measurements of several RNAs in the range of 2-6 nm were successful.
