(A) 1D triple receiver SIM-CP experiment for monitoring residual ¹H, and transferred ¹³C and ¹⁵N polarization. (B) Plot of the normalized intensities for SIM-CP polarization pathways obtained from the integrated intensities of ¹H, ¹³C, and ¹⁵N 1D spectra of fMLF tripeptide sample, at contact times ranging from 0 to 2 ms. (C) ¹H, ¹³C, and ¹⁵N 1D spectra at SIM-CP contact times 0 and 1 ms.
