  • Title: Heteronuclear dipolar recoupling in liquid crystals and solids by PISEMA-type pulse sequences.
    Author: Dvinskikh SV, Zimmermann H, Maliniak A, Sandström D.
    Journal: J Magn Reson; 2003 Sep; 164(1):165-70. PubMed ID: 12932469.
    Abstract:
    A pulse sequence is described for the recoupling of heteronuclear dipolar interactions under MAS. The method is similar to the PISEMA experiment, but employs a well-defined amplitude modulation of one of the two radio-frequency fields. The technique is used for measurements of 1H-13C dipolar couplings in unoriented solid and liquid-crystalline samples.
