Rotational Echo DOuble Resonance (REDOR) NMR is an oft-demonstrated tool for measuring distance between isolated IS spin pairs. Its application to more complex ISn spin networks (n〉1), however, is rare, as in these systems the interpretation of the results is model-dependent–while it is precisely the measurement of multiple distances which is required for molecular structure elucidation. Recently, aitch-theta-REDOR was introduced and was shown to improve interpretability at the cost of signal intensity. In this paper we analyze generalizations to the REDOR pulse sequence, and present a new experimental procedure which allows for simultaneous distance determinations in larger spin systems with improved signal intensity. Experimental data are presented for the IS2 spin system glycine-13C2-15N. © 2000 American Institute of Physics.
