Figure 3. Simulations show long-range spin correlations by the PELF-MIX pulse sequence.

Figure 3

SPINEVOLUTION simulations were performed on the spin system shown in Figure 1B. The strength of the dipolar coupling between H1 and X was νD1=4.46 kHz and the strength of the dipolar coupling between H2 and X was νD2=2.5 kHz. (A) Simulations of the PELF-mix pulse sequence (modeled as shown in the inset) were performed for various mixing times, tmix. The spin-bath containing different number of protons are considered in the simulations. (B) Dipolar coupling slices taken at the maximum of X-H2 crosspeak intensity for various sizes of the proton spin-bath.
