  • Title: REDOR-determined distances from heterospins to clusters of 13C labels.
    Author: Schaefer J.
    Journal: J Magn Reson; 1999 Mar; 137(1):272-5. PubMed ID: 10053159.
    Abstract:
    The use of rotational-echo double resonance NMR to measure distances from an observed tightly coupled cluster of 13C spins to a distant 15N, 31P, or 19F is practical if all homonuclear 13C-13C 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 19F-13C distances in p-trifluoromethylphenyl [1,2-13C2]acetate.
