摘要: A numerical assessment of the efficacy REDOR recoupling heteronuclear dipolar interactions employing adiabatic dephasing pulses has been carried out by considering an isolated coupled spin 1/2 I-S system. At moderate magic angle spinning frequencies in range 3–6 kHz and when CSA dephased spins is large, it shown that efficient broadband reliable distance estimates can be achieved even under conditions where a significant fraction rotor period occupied pulse. The with inversion demonstrated experimentally two model 15N-13C systems, (13C′,15N) Aib-(15N) Aib-NH2 (Aib = α-aminoisobutyric acid) (1-13C,15N) glycine.
