摘要：

The use of rotational-echo double resonance NMR to measure distances from an observed tightly coupled cluster of C-13 spins to a distant N-15, P-31, or F-19 is practical if all homonuclear C-13-C-13 dipolar interactions are suppressed by multiple-pulse decoupling during heteronuclear dipolar evolution. This scheme is first calibrated by experiments performed on multiply labeled alanines and then applied in the measurement of F-19-C-13 distances in p-trifluoromethylphenyl [1,2-C-13(2)]acetate.
