Accurate distances between two trityl paramagnetic tags site-specifically attached to DNA duplexes were measured by pulsed electron-electron double resonance spectroscopy at 180 and 260 GHz microwave frequencies. Up to a threefold increase in the sensitivity of 260 GHz PELDOR measurements was achieved by using shaped broad-band microwave pulses.
