rotational-echo double-resonance spectroscopy 31P–15N rotational-echo double-resonance spectroscopy 31P–15N REDOR NMR A magic angle spinning NMR experiment in which the evolution of dipolar couplings between 31P and 15N nuclei is controlled by applying pulses at appropriate points in the rotational period, allowing the determination of the size of the coupling and, thus, yielding distance information.
