如果在异核偶极演化过程中，所有同核C-13-C-13偶极相互作用都被多脉冲去耦合抑制，那么使用旋转回波双共振核磁共振来测量从观察到的紧耦合的C-13自旋到遥远的N-15、P-31或F-19的距离是可行的。该方案首先通过多标记丙氨酸的实验进行了校准，然后应用于对三氟甲基苯乙酸酯的F-19-C-13距离的测量。(C)1999年学术出版社。
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.
